Answer:
11
Step-by-step explanation:
First, we need to find the other angles. We'll do this by subtracting 180-141, giving us 39. This is one of the angles needed.
Next, we'll find the other angle by subtracting 180-127, giving us 53.
Now, we can set up the expression: 39 + 53 + 8y = 180
Adding like terms: 92 + 8y = 180
Now, subtracting 180-92 to give us 8y = 88
Diving both side by 8, gives us the value of y = 11.
3) 4r⁻³ · 2r² = 4·2 r⁽⁻³⁺²⁾ = 8 r⁻¹ = 8/r
4) 8k⁵
7) 6xy²
Answer:
{x,y}={1,7}
Step-by-step explanation:
Firstly, a straight line = 180 degrees.
Based on the statement above, we can create an equation of 180-95 = x
(Which is 85)
Now, we also know that all of the angles in a triangle add up to 180 degrees, so we can create this equation of 180- (85 + 50) = y
(Which is 45)
