Answer:
D. 180 ÷ 3 = m
Step-by-step explanation:
The sum of the angles in a triangle adds up to 180°.
Since equilateral triangles have 3 equal angles,
sum of the angles in the triangle= 3m
3m=180°
m= 180° ÷3
m=60°
Thus, 180÷3=m
Answer: A) 40%
B)30%
Step-by-step explanation:
A) becase 4/9 as a percentage is 0.444444% and I rounded it to 0.4% then turned it into 40% cause its outta 100

Answer:
So
And
Step-by-step explanation:
Given;
ABCD is a parallelogram and opposite sides of this parallelogram are parallel that is 'AB' parallel with 'DC' and 'BC' parallel 'AD'
Now joint the point 'A' and 'C' and we get two different triangle 'ABC' and 'ADC',
Reason: Given then mention that Alternate Interior angles are equal for parallel lines.
Reason: Given then mention that Alternate Interior angles are equal for parallel lines.
Reason: Common side.
Then
∴
By using diagonal 'BD' we could flow similar argument to prove that and also
∴
The first answer is correct .
Answer:
5 in.
Step-by-step explanation:
Given that
b1 = 12
b2 = 8
A = 50
Formula is (1/2)h(b1 + b2), on substituting
50 = 1/2 * h(12 + 8)
50 = 1/2 * h(20)
100 = 20h
h = 100/20
h = 5
The height is 5 in
