Answer:
17
Step-by-step explanation:
USING BIDMAS (Brackets Indices Division Multiplication Addition Subtraction)
6 − (9 − 2) + 3 × 6
9-2=7
3x6=18
6-7+18=17
Answer:
x = 21 degrees!
Step-by-step explanation:
3x + x + 96 = 180
4x +96 = 180
Subtract 96 from both sides!
4x = 84
Divide by 4 from both sides!
x = 21 degrees
3 is 13 more than 10, and 3 is 30% of 10, so 30% im pretty sure
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
