Answer:
B. m∠b + m∠d + m∠e = 180°
(Total angle in a triangle)
C. (m∠a + m∠b) - m∠d = m∠b
(Alternate angles)
E. (m∠a + m∠b + m∠c) = (m∠b + m∠d + m∠e)
(Supplementary angles)
Answer:
162
Step-by-step explanation:
6x+7x=364 suppose
13x=364
X=364/13=27
then,
red marbles=6x
=6×27=162
We use tan ratio to solve this problem. Look into my attachment for better understanding.
tan x = the side in front of the angle/ the side adjacent to the angle
tan x = 50/75
tan x = 2/3
x = tan⁻¹(2/3)
x = 33,69
x is approximately 34°
