Answer:
b
Step-by-step explanation:
u can use the ration method
15:15+36
20:6x-7
then cross multiply
and x =12.5
x = 12.5
The large outer triangle and the small inner triangle are similar, thus the ratio of their corresponding sides are equal, that is
= = ( cross- multiply )
15(6x - 7) = 1020 ( divide both sides by 15 )
6x - 7 = 68 ( add 7 to both sides )
6x = 75 ( divide both sides by 6 )
Ratios that are equivalent to each other are considered equivalent ratios. For example, 2:6 is equal to 6:18
its the first one.
x =60°
