Answer:
Angle A= 120⁰.. Angle B=60⁰
Step-by-step explanation:
To find angle A, you subtract 60 from 180, which would be 120. Angle A and 60⁰ are supplementary angles, meaning they have to add up to 180.
To find angle B, you take 360, since all the interior angles of that shape add up to 360.
360-90-90-120=60
Answer:
(4,-2)
Step-by-step explanation:
The reason why it's 4,-2 is because 5 which is the x value is subtracted by 1 since its translated 1 unit to the left, and the -2 which is the y-value is translated 4 units down which means you subtract 2 by 4. Pro tip: when translating the x-value left you subtract and if you translate it to the right you add. If you translate the y-value down you subtract and if you move it up you add.
Answer:
x is approximately 11.5
Explanation:
10x - 20 + 7x + 4 = 180
17x - 16 = 180
17x = 196
x is approximately 11.5
