Answer:
Angle of A = 90 degree-62 degree = 28 degree.
Step-by-step explanation:
tan (62) = opposite / adjacent = 10 / a ---> a = 10/tan (62) = 10/ 1.88 = 5.319
cos (62) = a/c --->c = a/cos (62) = 5.319 / 0.47 = 5.3 / 0.47 = 11.3
or another way.
sin (62) = 10 /c ---> c = 10/ sin (62) = 10 / 0.88 = 11.3
So Angle of A = 28 degree.
a = 5. 3
c = 11.3.

Step-by-step explanation:
Answer:
answers below and explained
Step-by-step explanation:
a) 2 (2 times 3) + 5 (3)
2 (6) + 5 (3)
12 + 15
= 27
b) a = 3 + 3
a = 6
c) 3(2a+1) - 6a + 7 = 10
6a + 3 - 6a + 7 = 10
3 + 7 = 10
