Answer:
(a) x = 22
(b) 46°
(c) 44°
(d) 180°
Step-by-step explanation:
Because the sum of the interior angles of a triangle is 180°, we know that the sum of the acute angles in a right triangle is 90°.
<h3>(a) </h3>
The sum of the marked acute angles is 90°.
2x +(3x -20) = 90
5x = 110 . . . . . . . . . . add 20, collect terms
x = 22 . . . . . . . . . divide by 5
__
<h3>(b) </h3>
∠CBA = (3x -20)° = (3·22 -20)° = 46°
__
<h3>(c)</h3>
∠CAB = 2x° = 2(22)° = 44°
__
<h3>(d)</h3>
The sum of a triangle's interior angles is 180°.

7 cabins takes 14.7 trees
Step-by-step explanation:
divided 10.5 by 5= 2.1 trees per cabin
2.1 x however many cabins your gonna build
Answer:
6.4/7.7 is the ratio
Step-by-step explanation:
The bottom triangle matches the 50 40 90 angle, so the ratio of the triangle length is consistent
