Hello! I need some help figuring out what I did wrong here. I understand for the most part but I messed up somewhere. Work would be nice so I can visually see the right process!
Answer:
x = 23
Step-by-step explanation:
Here, we want to find the value of x
To do this, we are to use the sine rule
But first, we need the measure of the last angle of the triangle
Mathematically, the sum of the angles in a triangle is 180
Thus;
B + 25 + 120 = 180
B + 145 = 180
B = 180-145
B = 35
Mathematically, we have the sine rule as; the ratio of the measure of the side of a triangle and the sine of the angle that faces the side is constant in a triangle
Thus, we have that
x/sin 120 = 15/sin 35
x sin 35 = 15 sin 120
x = (15 sin 120)/sin 35
x = 22.65
To the nearest whole number, x = 23

Name the triangle by looking at its angles.
Answer:
I think it's obtuse please don't come at me if I'm wrong.
it would be a right triangle because there’s a corner. obtuse and acute triangles have points.
PLEASE GEOMETRY HELP WILL MARK BRAINLIEST!!!
Answer:
3240°
Explanation:
The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.
Determine the type of triangle that is drawn below.
Answer:
Scalene Right.
Step-by-step explanation:

Solve this for the brainlist
Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y = [tex]\sqrt{400}[/tex] or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=[tex]\sqrt{500}[/tex] ≈ 22.4

Henry has a bag containing 39 letter tiles, some consonants, and some vowels. He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?
Answer:
21 consonant tiles
Step-by-step explanation:
Henry has a bag containing 39 letter tiles, some consonants, and some vowels.
He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?
Step 1
We add up the number of tiles that he pulls out of the bag
= 7 consonant tiles + 6 vowel tiles
= 13 tiles
Step 2
We divide the total number of tiles in the bag by the total number of tiles that was pulled out of the bag
= 39 tiles ÷ 13 tiles
= 3
Step 3
The most likely number of consonant tiles in Henry's bag is calculated as:
3 × The number of consonant tiles that was pulled out of the bag.
Hence:
3 × 7 consonant tiles
= 21 consonant tiles.
Therefore, the most likely number of consonant tiles in Henry's bag is 21 consonant tiles.
Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No
Answer:
No.
Step-by-step explanation:
We substitute the values x = 2 and y = -4 into the inequality.
Left side = 2(2) - 3(-4) = 4 + 12
= 16
Now the right side is 15 so we get 16 < 15 which is incorrect.
So (2, -4) is not a solution.

4.John purchased a roll of cloth 2m long for $205.00 . He resold the cloth in lengths of 250 mm for $40.00 per length. Calculate profit he made.
Answer:
Step-by-step explanation:
Answer:
$115.00
Step-by-step explanation:
1m = 1000mm
2m = 1000 × 2 = 2000mm
2000÷ 250 = 8
he sold 8 piece of cloth
8× 40 = 320.00
profit
320.00 - 205.00 = $ 115.00
Alejandra va pintar la puerta de su casa . Tiene 1.3L de pintura azul y le agrega 1/5 de L de pintura blanca cuantos litros de esta mezcla tiene para pintar
Responder:
1,5 litros
Explicación paso a paso:
Dado que :
Volumen de pintura azul = 1,3 L
Volumen de pintura blanca = 1/5 L
Expresando el volumen de pintura blanca como decimal = 1/5 = 0,2 L
Mezcla de las pinturas blanca y azul:
Volumen de mezcla:
Volumen de pintura azul + Volumen de pintura blanca
1,3 L + 0,2 L
= 1,5 L de pintura
Carmen bought a new body lotion bottle which contains 40-oz. After some time, she used 8-oz. Enter the percentage of ounces Carmen has left of the body lotion.
Answer:
carmen has 32-oz of lotion left
Answer:
80%
Step-by-step explanation:
40-8=32
What % of 40 is 32?
P% of 40 is 32
Equation: P% * X = Y
Solving our equation for P
P% = Y/X
P% = 32/40
p = 0.8
Convert decimal to percent:
P% = 0.8 * 100 = 80%

C= (8,0) and D = (0, -6) the distance between is
Answer:
10
Step-by-step explanation:
First,
(x1, y1) = (8, 0)
(x2, y2) = (0, -6)
Second,
√(x2 - x1)² + (y2 - y1)²
= √(0 - 8)² + (-6 - 0)²
√(-8)² + (-6)²
= √64 + 36
Lastly,
= √100
Distance = 10 :)
