Answer:
15
Step-by-step explanation:
Opposite sides in a parallelogram are equal.
2x - 5 = x + 10
Subtract x and add 5 on both sides.
2x - x = 10 + 5
Combine like terms.
x = 15
Answer:
Slope = y2-y1/x2-x1
Slope = (7-3)/(3-1)
Slope = 4/2
Slope 2
Let me know if this helps!
Answer:
117 units
Step-by-step explanation:
if you use the ratio of the two longest sides then you can find all side lengths
= 
; x = half of 52, or 26
= 
; 20x = 52 · 15
20x = 780
x = 39
add to get perimeter: 52 + 26 + 39 = 117 units
Answer:
Angle 1: 95 degrees
Angle 2: 85 degrees
Angle 3: 95 degrees
Step-by-step explanation:
Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°
So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees
85 + ? = 180
?=95
So both angle 1 and 3 equal 95 degrees
