Answer:
d)
true
Step-by-step explanation:
- x - 4y = - 10
x + 4y - 10 = 0
a)
3 + 4×2 - 10 = 0
3 + 8 - 10 = 0
11 - 10 ≠ 0 (false)
b)
- 3 + 4×3 - 10 = 0
12 - 3 - 10 = 0
12 - 13 ≠ 0 (false)
c)
false
d)
true
This is easy go on khan academy an look up how to find the y coordinate
Given: ∠A is a straight angle. ∠B is a straight angle.
We need to Prove: ∠A≅∠B.
We know straight angles are of measure 180°.
So, ∠A and <B both would be of 180°.
It is given that ∠A and ∠B are straight angles. This means that <u>both angles are of 180°</u> because of the <u>the definition of straight angles</u>. Using <u>the definition of equality</u>, m∠A=m∠B . Finally, ∠A≅∠B by <u>definition of congruent. </u>
