linear pairs are supplementary so their sum equals 180°
(3x - 30) + (x + 76) = 180
4x + 46 = 180
4x = 134
x = 33.5
∠1: 3x - 30 = 3(33.5) - 30 = 70.5
∠2: x + 76 = (33.5) + 76 = 109.5
Answer: ∠1 = 70.5°, ∠2 = 109.5°
Answer:
x = 2, y = 3.
Step-by-step explanation:
As it is a parallelogram opposite sides are equal so we have the equations:
3y = 9
y = 3.
2x + 4 = 8
2x = 4
x = 2.
Simplifying the expression gives 36x^2 - 82x - 10 = 0
<h3>How to simplify the expression</h3>
Given the expression;
4x-5/3+2x=7+2/9x+2
Cross multiply
Expand the bracket
Collect like terms
36x^2 + 8x - 45x - 27x - 18x = 0
Add the like terms
36x^2- 82x - 10 = 0
Thus, simplifying the expression gives 36x^2- 82x - 10 = 0
