Answer:
x = 28⁰
Step-by-step explanation:
sum of the angles of a triangle = 180⁰
∠A + ∠B + ∠C = 180⁰
∠A = 5x - 60⁰
∠B = 2x + 40⁰
∠C = 3x - 80⁰
<h2>:- Solution</h2>
∠A + ∠B + ∠C = 180⁰
5x - 60 + 2x + 40 + 3x - 80 = 180⁰
5x + 2x + 3x - 60 + 40 - 80 = 180⁰
10x - 20 - 80 = 180⁰
10x - 100 = 180⁰
10x = 180 + 100⁰
10x = 280⁰
x = 280⁰/10
x = 28

Answer:
5. 87.5 mi.
6. 18 - 8x = -6x
Explanation:
5. Every one inch on the map is equal to 25 miles as the actual distance. To find how many miles 3.5 inches on the map is, multiply 3.5 by 25:
3.5 · 25 = 87.5 mi.
6. Translate the verbal sentence into numbers and symbols:
18 - 8x = -6x
(a number is referring to a variable, as shown by x)
