It is 5, I hope this answers your question
Answer:
11) x = 11
12) x = 11
Step-by-step explanation:
11) Δ RQP and Δ RLK are similar.
Hence, the ratios of the corresponding sides of the two triangles will be constant.
So,
⇒
⇒
⇒ x - 4 = 7
⇒ x = 11 (Answer)
12) Δ QRS and Δ QDC are similar.
So,
⇒
⇒ 2x - 14 = 8
⇒ 2x = 22
⇒ x = 11 (Answer)
I think the answer is a=7b*9/2=31.5M
Scalene right triangle-
None of the angles are congruent so it’s scalene, but since a it has a 90 degree angle it is also a right triangle
