The side of the square is (12x+52)/4=3x+13.
X/15=4/16 def of similar triangle by AAA
x = 60/16=5/2
7 + 7 + (-1)
7 + 7 - 1
13
Hope this helps :)
Answer:
side c = 10.2
A = 52.6°
B = 37.4°
Step-by-step explanation:
c² = 8.1² + 6.2²
c² = 104.05
c = 10.20049018
Using cosine law:
8.1² = 10.2² + 6.2² - 2(10.2)(6.2)cos
cosA = 7687/11648
A = 52.57199409
A = 52.6°
B = 180 - 90 - 52.6 = 37.4°
Answer:
its B
