Answer:
16 feet
Step-by-step explanation:
As said in the problem statement, the angles between the top of the house, the mirror, and the ground and between Sarah's eyes, the mirror, and the ground are congruent.
We also know that Sarah and the house are perpendicular to the ground.
So if we draw a triangle from the top of the house, to the mirror, to the bottom of the house, and another triangle from Sarah's eyes, to the mirror, to Sarah's feet, we get two triangles that have the same angles. Therefore, the triangles are similar, and we can write a proportion:
4 / 5 = h / 20
h = 16
The house is 16 feet tall.
Answer:
76%
Step-by-step explanation:
24% of 700=168
100-24=76
7 because there is 7 zeros
Answer:
Step-by-step explanation:
<u>It shows combination of:</u>
- m∡EBD = 180° and
- m∡EBC + m∡CBA + m∡DBA = m∡EBD
<u>m∡EBD in the first equation is substituted with 180° in the second and it results in:</u>
- m∡EBC + m∡CBA + m∡DBA = 180°
<u>Correct choice is:</u>
The first option and the third one
