We are dealing with similaraty and similar shapes length are in proportion so we are going to set up an proportion.
Length of left triangle small side/ Length of left triangle long side= length of right triangle small side/length of right triangle long side
4/10=x/20
Cross multiply: 10x=80
x=8
Answer:
Step-by-step explanation:
<u>As the triangles are similar, their corresponding sides will have same ratio:</u>
- left short side /right short side = left long side / right long side
or simpler
<u>Substitute values to find the missing one:</u>
- 4/x = 10/20
- 4/x = 1/2
- x = 4*2
- x = 8
The missing side is 8 inches long

Answer:
a ≈ 1.8
Step-by-step explanation:
a / sin (180 - 105 - 15)° = 2 /sin 105°
a = (2 /sin 105°) x sin 60°
a = (2 / 0.97) x 0.87
a = 1.79 (≈ 1.8)
