What is X? Please help

Mathematics
1 answer:
Karolina [17]2 years ago
7 0

Answer:

70

Step-by-step explanation:

Given is an isosceles triangle.

Angles opposite to equal sides are equal.

Therefore,

x° + x° + 40° = 180°

2x° = 180°- 40°

2x° = 140°

x°= 140°/2

x° = 70°

x = 70

What is 55 percent of 160?
Maurinko [17]

Answer: 88

Step-by-step explanation: To find 55% of 160, first write 55% as a decimal by moving the decimal point two places to the left to get .55.

Next, the word "of" means multiply, so we have (.55) x (160).

(.55) (160) = 88

Therefore, 55% of 160 is 88.
