Answer:
<h3> ∠R = 69</h3>
Step-by-step explanation:
<h2>Angle sum property</h2>
Sum of all angles of triangle = 180
5x - 11 + 3x - 3 + 3x + 18 = 180
5x + 3x + 3x -11 - 3 + 18 = 180
Combine like terms
11x + 4 = 180
11x = 180 - 4
11x = 176
x = 176/11
x = 16
∠R = 5x - 11
= 5*16 - 11
= 80 - 11
= 69
Step 1: Add 3x to both sides.d−3x+3x=−9+3xd=3x−9 = ANSWER
Can you possibly help me on my recent question?
answer:
d: 30
all angles in a triangle have a sum of 180 degrees. Just add 50 and 100 (so 150) and do 180-150=30.
for this question you would need to utilize ratios to find the side lengths. For example, set up a ratio between the big triangle with the small triangle to find a side length
