A triangle has two sides of 30 meters and 26 meters, and the angle between them is an obtuse angle. If the area of the triangle is 300 sq. Meters, find the measure of the obtuse angle (to the nearest degree).
Answer:
130°
Step-by-step explanation:
Using the formula
Area of the triangle = 1/2 absin theta
a and b are the sides
theta is the obtuse angle
Given
a = 30m
b = 26m
Area = 200m²
Required
theta
Substitute into the formula;
300 = 1/2(30)*(26)sin theta
300 = 15*26sin theta
300 = 390 sintheta
sin theta = 300/390
sin theta = 10/13
sin theta = 0.7692
theta = arcsin(0.7692)
theta = 50.28degrees
Since the angle is obtuse, it must lie between 90 and 180degrees
theta = 180-50.28
theta = 129.72°
Hence the measure of the obtuse angle to the nearest degree is 130°
The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, 1).
y = 1 over 2 x − 3 over 2
y = − 1 over 2 x − 3 over 2
y = 1 over 2 x + 3 over 2
y = negative 1 over 2 x + 3 over 2
Answer:
third option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 5 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (- 1, 1) into the partial equation
1 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = 1 + [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← equation of perpendicular line

PLEASE HELp tHHIS IS dUE IN AN HOUR!!!!! ITS MY LAST QuESTION Tony and Tiffany colleg\ct semi-precious stones. At the Rockhound Hut, Tiffany paid $38 for 9 pounds of snowflake obsidian. At the Solid Rock Shop, Tony paid $19 for 3 pounds of the same type of stone. What did each person pay per pound and who made the btter buy?
Answer:
Tiffany purchase the better buy.
Step-by-step explanation:
given data
Tiffany paid = $38
snowflake obsidian = 9 pounds
Tony paid = $19
same type of stone = 3 pounds
solution
Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each
so for Tiffany
= $38 ÷ 9
= $4.22 per pound
and for Tony
=$19 ÷ 3
= $6.33 per pound
so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound
so here whole $2.11 more than Tiffany
so that with this Tiffany purchase the better buy.

Marisol constructed a triangle. One angle in the triangle has a measure of 40°. Another angle in the triangle has a measure of 80°. What is the measure, in degrees, of the third angle in Marisol’s triangle?
Answer:
A triangles angle always equal to 180 degrees. So if you add up what you already have which is 80+40=120

why do my eyes hurt after looking at a picture of the sun;(
what would happen if i hired two private investigators to follow each other...
Answer:
1. The Pacific Ocean has an area of 63.78 million square miles, an average depth of 3,688 meters, and a volume of 660,000,000km cubed.
2. Use these guidelines when developing questions:
Plan your questions.
Know your purpose.
Open conversation.
Speak your listener's language.
Use neutral wording.
Follow general questions with specific ones.
Focus your questions so they ask one thing at a time.
Ask only essential questions.
3. I don't know XD
4. On an adventure that humans don't know about
5. Depends on the picture of the sun.
6. They would probably be so confused while they tried to follow each other XD

Answer:
It will not fit.
Step-by-step explanation:
The mat is 1/2 by 2/3. So, lets add that together.
1/2 + 2/3 = 7/6
Now there are 24 sixths in a fourth.
So subtract 24 - 4 = 17
Final answer would be 17/4. Still way to big to fit in the 1/4 step.
Hope this Helps!!:)

In 1 minute, Alex can type 44 words. While working on a project, Alex types from 10:00 AM until 1 AM, He takes a break from 1 0:25 AM to 10:40 AM. At the same rate, how many words did he type?
Answer:
39600 words
Step-by-step explanation:
Given data
In 1 minute, Alex can type 44 words
from 10:00 AM until 1 AM= 15 hours
15 hours to minutes= 15*60= 900 minutes
Hence in In 1 minute, Alex can type 44 words
in 900 minutes he will type x words
cross multiply
x= 900*44
x= 39600 words
Hence he will type 39600 words

Keith mowed his aunt's yard 12 times. Each time, he mowed for 1.75 hours and he earned $8.40 per hour. How much money, to the nearest cent, did Keith earn mowing his aunt's yard?
Answer: $176.40
Step-by-step explanation:
Keith mowed the yard 12 times.
Each time he mowed took 1.75 hours.
The number of hours he took in total is therefore:
= 12 * 1.75 hours
= 21 hours
He gets paid $8.40 for every hour he works. For the 21 hours therefore, he would earn:
= 8.40 * 21 hours
= $176.40

Step-by-step explanation:
A quadrilateral has the following vertices on a coordinate plane:
================================================
Explanation:
We'll only focus on points J and K.
J = (3, -6)
K = (-1, -6)
Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates
3 minus (-1) = 3 - (-1) = 3 + 1 = 4
Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.
This means segment JK is 4 units long.

The answer is -10
