Answer:
∠ B = 19°
Step-by-step explanation:
note ∠ C = 90° ( angle in a semi- circle )
The sum of the 3 angles in the triangle = 180°, thus
∠ B = 180° - (90 + 71)° = 180° - 161° = 19°
Step-by-step explanation:
65% of 80= 80×0.65 = 52mins
5/8 of 80= 5/8×80 = 50 mins
<h2>
more mins = 52-50= <em><u>2</u></em><em><u> </u></em><em><u>m</u></em><em><u>o</u></em><em><u>r</u></em><em><u>e</u></em><em><u> </u></em><em><u>m</u></em><em><u>i</u></em><em><u>n</u></em></h2>
X=12 because a half of 12 is six.
The answer is 60
because first you subtract 10 on both sides
then multiply 4 on both sides getting v=60
