Answer:
X = 45
Step-by-step explanation:
Answer:
a = b = 1
Step-by-step explanation:
The triangles are similar thus ratios of corresponding sides are equal, that is
= ( cross- multiply )
10b = 10 ( divide both sides by 10 )
b = 1
and
= ( cross- multiply )
10a = 10 ( divide both sides by 10 )
a = 1
Thus a = 1 and b = 1
The answer would be -84.
Here are the steps I did.
1. Simplify 4 + 8 to 12 ( -7 * 12 )
2. Now lastly simplify and u get -84.
U say the answer is D 7$......
