You know from trigonometry that AB = 15 units, so the area of the larger triangle ACB is (1/2)*15*15 = 112.5 units^2.
Then the area of triangle ADE is
.. (112.5 -62.5) = 50 . . . . units^2
<span>We'll do two by two,
1.4 – 5.5= -4.1
</span><span>– 1.73 + 1.8= 0.07
Leaving </span><span>– 1.09,
You get </span>
=-4.1+<span> 0.07- 1.09
=-4.03-1.09
=-5.12</span>
Answer:
y = 3
Step-by-step explanation:
The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
y² = 63 ( take the square root of both sides )
y = 
= 
= 
× = 3
