CAN ANYONE HELP ME WITH QUESTION 7

Answer:
X = 4
Step-by-step explanation:
The angles of a triangle add up to 180 degrees and this is an equilateral triangle which means that all the angles are the same. which means you set up the equation:
10x + 20 + 10x + 20 + 10x + 20 = 180
Simplify: 30x + 60 = 180
- 60 - 60
You have : 30x = 120
(Divide by 30)
You end up with: X = 4
Answer:
x = 4.
Step-by-step explanation:
Each angle in an equilateral triangle is 60 degrees, so we have:
10x + 20 = 60
10x = 40
x = 4.

Answer:
(1 + 4²) x (√25) ÷ 10 x (√4) = 17
Step-by-step explanation:
(1 + 16) x (5) ÷ 10 x (2) = 17
(17) x (5) ÷ 10 x 2 = 17
(85 ÷ 10) x 2 = 17
(8.5) x 2 = 17
17 = 17
Hope this helps buddy!
