Answer:
B. 40
Step-by-step explanation:
It looks like a 90-degree angle so...
90 - 30 = 60
60 - 20 = 40
40 would be your final answer.
Based on the angles addition theorem, the measure of the original angle = 44°.
<h3>What is the Angles Addition Theorem?</h3>
The angles addition theorem states that if an angle is bisected to form two smaller angles, then the sum of the measures of the two smaller angles equals the measure of the original angle that is bisected.
Given that the two smaller angles formed when bisected are: (3+30)° and (5+6)°. Based on the angles addition theorem:
The measure of the original angle = (3+30)° + (5+6)°
The measure of the original angle = 33° + 11°
The measure of the original angle = 44°

Answer:
Step-by-step explanation:
Tri WYV is a right triangle
WYV ~ SVU Reflective property
Angle YVW = Right angle, Right Triangle property
SVY ~ WVU by reflective property
VW = VU by perpendicular property
Answer:72.6
Step-by-step explanation:
Answer: 
, 
, 
, 15/2, 7.5
Step-by-step explanation: This is a bit tricky because 15/2 is equal to 7.5 !!
√40 = 6.32455532
7 1/5 = 7.2
3√6 = 7.348469228
15/2 = 7.5
7.5 = 7.5
