Answer:
The last one, angle D equals to angle T
Step-by-step explanation:
Using the theorem of the triangle we know that the total number measure of the angles is 180 degrees. Therefore, solving the second triangle will give us that the angle T is equal to 60.
This is equal to angle D.

Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula
225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P = 
P= 56.89202
So measure of angle P is 57 degrees
The answer is c. i hope i helped
35x+5= 45
Subtract 5 on both sides.
35x=40
Divide both sides by 35.
x= 8/7 (simplified)
I hope this helps!
