Answer:
B = 145°
Explanation:
Sorry but m∠C > 90° how could it be 35° ?
However if you still need an answer:
B = 180 - C
B = 180 - 35
B = 145°
Step-by-step explanation:
The first one will be:
7x^6 - 7x^5 +28x - 4x² - 60
And the second:
-9x⁴-3x²-4x²+5x
74 + 35 + 16 + 45 =
= 74 + 16 + 35 + 45
= 70 + 4 + 10 + 6 + 30 + 5 + 40 + 5
= 70 + 10 + 4 + 6 + 30 + 40 + 5 + 5
= 80 + 10 + 70 + 10
= 80 + 10 + 10 + 70
= 100 + 70
= 170
