Find the measure of angle 3=

Mathematics
1 answer:
andre [41]3 years ago
5 0

Answer: <em>50°</em>

Step-by-step explanation:

<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>

<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>

<em>Now every triangle must add up to 180°</em>

<em>so lets take the angles we have now</em>

<em>90° +40°=130°</em>

<em>now take that 130°</em>

<em>180°-130°=</em><em>50°</em>

<em>Now check your work</em>

90°+40°+50°=180°

Angle 3 is 50°

48 is what percent of 160
professor190 [17]
Percent formula : is/of = %/100

is = 48
of = 160
% = x

48/160 = x/100
cross multiply
160x = 4800
x = 4800/160
x = 30......so 48 is 30% of 160
