Answer: angle 2 is 49°
explanation: the interior angles of all triangles add up to 180°, so just subtract the known angles from 180 to get the unknown angle:)
Answer:
72 sq ft.
Step-by-step explanation:
Surface area of Triangular prism=[2*(1/2)*3*4]+(5*5)+(3*5)+(4*5)=12+25+15+20=72 sq ft.
<span>Since it is isosceles, we know that the other base angle is also 40°
</span><span>Three interior angles of every triangle totals 180°
</span><span>x° + 80° = 180°
</span><span>x° = 100°</span>
15% of a number is 45
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300
Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45
45 is 15% of 300.
