Answer:
A triangle's total is 180 degrees. 90 is a right angle. 20 is the angle for A. That would mean the value of 90+20=110. 180-110=70 B is 70
Answer:
22 / 9
Step-by-step explanation:
25 - 3 = 22
10 - 1 = 9
22 / 9
You cannot simplify 22 / 9
Add the coefficients of like terms.
a) (6x³ +8x² -2x +4) + (10x³ +x² +11x +9)
= (6+10)x³ + (8+1)x² + (-2+11)x + (4+9)
= 16x³ +9x² +9x +13
b) (16x³ +9x² +9x +13) + (3x -2)
= 16x³ +9x² + (9+3)x + (13-2)
= 16x³ +9x² +12x +11
Answer:
b = 29.0, A = 123.9°, C = 20.1°
Answer:
Slope is -5/3
Step-by-step explanation: when you look at the graph, the line is descending meaning it will be a negative, so we can eliminate the answers that are positive leaving us with 2 options. Then we have to do rise/run, you figure that out by counting how many points the line goes up and to the right or left, and intersects with the line
