Answer:83 and 97
Step-by-step explanation:
Let the angle be y
The second angle will be y+14
A supplementary angle equals 180°
y + y + 14=180
2y+14=180
2y=180-14
2y=166
y=166/2
y=83
The first angle is 83.
Second angle will be 83+14=97.
32.5 degrees is the answer
Answer:
2.8a²+0.9a - 1.2
Step-by-step explanation:
Given the expression 0.3(3a-4)-0.05(8a)(-7a)
Expand using the distributive law
0.3(3a-4)-0.05(8a)(-7a)
0.3(3a)-0.3(4)-0.05(8a)(-7a)
0.9a-1.2 - 0.05(8a)(-7a)
0.9a - 1.2 + 2.8a²
Rearrange
2.8a²+0.9a - 1.2
Hence the required expression is 2.8a²+0.9a - 1.2
