Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
Answer=Order of operations
The order of operations (which we use PEMDAS to help us remember) tells you which operation to do first.
Answer:
The answer is (6,9)
Step-by-step explanation:
We simply need to find two numbers that perfectly fits the equation. That is, 2 numbers in which when we substitute the value for x and y works perfectly.
First option is wrong.
3x + 2y = 36
Here, x = 6 and y = 0
Hence, 3(6) + 2(0) = 18 which is wrong.
3rd option is wrong
Here x = 6 and y = -9
3(6) + 2(-9) = 0
Last option is wrong
Here x = 6 and y = 6
3(6) + 2(6) = 18 + 12 = 30.
2nd option is correct
Here x =6 and y = 9
3(6) + 2(9) = 18 + 18 = 36
-6, -4, -1, 3, 7
Hope this helps!
We can use the Sine Law:
a / sin A = b / sin B
16 / sin 22° = 25 / sin B
16 / 0.3746 = 25 / sin B
sin B = 25 · 0.3746 / 16
sin B = 0.5853
∠B = sin^(-1) 0.5853
∠B = 35.83° ≈ 35.8°
Answer: b. 35.8°
