Answer:
Step-by-step explanation:
I'm not sure you will be satisfied with this but the area of a octagon is given by Area =2(1+√2)a²
Using this formula you get
a = 11 cm
Area = 2*(1 + √2)11²
Area = 2*(1 + 1.4142)*121
Area = 2*(2.4142)*121
Area = 4.8284*121
Area = 584.24

A quadrilateral has the following vertices on a coordinate plane:
Answers
================================================
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.

what transformation will take triangle GBC onto triangle ABC?
plz help it’s due today
Answers
Answer:
Reflection of ΔGBC on side BC.
Step-by-step explanation:
Transformation is the process by which the orientation or dimension of a given shape or figure is adjusted by some method of processes to produce an image with a required property.
From the given diagram, triangles ABC and GBC are congruent, so that;
AC ≅ GC
AB ≅ GB
BC is a common side to both triangles
Therefore, the appropriate transformation that would take ΔGBC onto ΔABC is reflection on side BC.

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?
Answers
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

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).
Answers
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°
