Answer:
the answer is 4 (option C)
Step-by-step explanation:
Since the triangles are similar, and in triangle UTV both sides are equal, we can consider QTR also has two equal sides.
therefore, the equation forms:
13x + 3 = 55
13x = 55 - 3
13x = 52
x = 52/13
x = 4
; where a = 1, b = -4 and c = 8
Answer:
A = 58.7 degrees
B = 66.9 degrees
C = 34.1 degrees
Step-by-step explanation:
<u><em>For <A:</em></u>
Tan A =
Tan A =
Tan A = 1.6
A =
A = 58.7 degrees
<u>For <B:</u>
Sin B =
Sin B =
Sin B = 0.92
B =
B = 66.9 degrees
<em><u>For <C:</u></em>
Sin C =
Sin C =
Sin C = 0.56
C =
C = 34.1 degrees
