Answer:
r = 14
Step-by-step explanation:
1. Because the two angles are a pair of opposite angles formed by intersecting lines, they're vertical angles/congruent.
2. To find the value of r, we can write an equation of: 
3. (Solving)
Therefore, r = 14.
Answer:
the second one the x-axis is the horizontal one
Step-by-step explanation:
Answer:
k=27
Step-by-step explanation:
Answer:
Gold square = 4
Blue triangle = 3
Step-by-step explanation:
Red hexagon = 6, and there are 4 red hexagons. So the total is 24.
Therefore, the total on the other side must also be 24.
That means the 4 blue triangles add up to 12, and the 3 gold squares add up to 12.
So each blue triangle is 3, and each gold square is 4.
Area = 1/2bh (base · height)
5 · 15 = 75
75 · 0.50 or 75/2 = 37.50
Area = 37.50
Hope this helps!
