3rd and 5th one I think sorry if I’m wrong
Answer:
∠A = 166°
Step-by-step explanation:
We can imagine the parallel line to the left as a shifted version of the one on the right. As we move it further left along the line the in middle (called a <em>transversal</em>), ∠B will slide closer and closer to ∠A. Eventually, the two will totally coincide, showing that ∠B ≅ ∠A. We call ∠A and ∠B <em>corresponding angles</em>, because they can be made to perfectly overlap in that way.
Since corresponding angles are congruent, their measures must be equal, so in this example, we can say that
, and since 
and 
,
To solve for <em>x</em>, we can subtract 3x and 40° from both sides:
and divide both sides by 4:
We can now replace <em>x </em>with 18° in our expression for ∠A to find
Answer:
P.354
Step-by-step explanation:
Answer:
The reflection image of P(0, 0) after two reflections is (8,-6)
Step-by-step explanation:
step 1
Find the coordinates of point P after reflection across x=4
we know that
The distance from point P to the line x=4 is equal to 4 units
so
(0,0) -----> (4+4,0) ----> (8,0)
The reflection image of P is (8,0)
step 2
Find the coordinates of point (8,0) after reflection across y=-3
The distance from point (8,0) to the line y=-3 is equal to 3 units
so
(8,0) -----> (8,-3-3) ----> (8,-6)
Answer:
37.5
Step-by-step explanation:
If you cut 600 in half 4 times the first time it will be 300 because 600/2 is 300. The second time it will be 150 because 300/2 is 150. The third time it will be 75 because 150/2 is 75. The fourth time it will be 37.5 because 75/2 is 37.5, so that is the answer.
If this helps please give me brainliest. Thx :)
