Hello!
<h2>Answer:</h2><h2 />______________________________________________________
<h2>Explanation:</h2>To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = bh
A = (12 · 5)
A = (60)
A = 30 mm²
Inner:
A = bh
A = (4 · 3)
A = (12)
A = 6
30 - 6 = 24
Answer:
60
Step-by-step explanation:
using the rule of radicals

=
given
3 × 5
= 3 × 5 × ×
= 15 ×
= 15 × 4
= 60
Answer:
Step-by-step explanation:
The first triangle right isosceles. The sides opposite the 45° angles are the same length.
x = 13
By the Pythagorean Theorem, y = 13√2
:::::
Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.
x = 6
y = 3√3
:::::
The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.
x = 17√3
The other triangle is right isosceles.
z = 34
y = 34√2
