a ≈ 5.2, B ≈ 50°, C ≈ 95°
Solution:
Given data:
A = 35°, b = 7, c = 9
Using cosine law,




Taking square root on both sides.
a ≈ 5.2
Using sine law,


Multiply by 7 on both sides.

Switch the sides.
Sin B = 0.772

B ≈ 50°
Sum of all the angles of a triangle = 180°
A + B + C = 180°
35° + 50° + C = 180°
85° + C = 180°
C = 180° - 85°
C = 95°
Hence a ≈ 5.2, B ≈ 50°, C ≈ 95°.
Answer:
-11.3
Step-by-step explanation:
Combine the negative terms, obtaining -3.5 - 12.8, or -16.3.
Next, combine 5 and this last result: -16.3 + 5 = -11.3
Answer:
3^2/15
Step-by-step explanation:
(^5sqrt3^2)^1/3
(3^2/5)^1/3
multiply the powers
3^2/5*1/3
3^2/15
The anwser is 13 because the quantity increased by 1 is 14
