You are correct, it would be a reflection across the y-axis. I am great at visualizing but for those who are not (Not saying you) all they have to do is cut out a parallelogram and mimic the movements.

Determine the area of the composite figure.

MaRussiya [10]

Answer:

$110\ in^2$

Step-by-step explanation:

$1)\ A_1 = b * h_1 = 10 * 8 = 80\ in^2$

$2)\ A_2 = \frac{b*h_2}{2} = \frac{10*(14-8)}{2} = \frac{10*6}{2} = \frac{60}{2} = 30\ in^2$

$3)\ A = A_1 + A_2 = 80 + 30\ in^2 = 110\ in^2$

In any triangle, the three angles add up to 180°. In my triangle, the first angle is twice the second angle, and the second angl

nekit [7.7K]

Answer:

<h3>Therefore the angles of the triangle are 52.5°, 105°,49.5°.</h3>

Step-by-step explanation:

Triangle:

The sum of the angle of triangle = 180°

Heron's formula the area of triangle = $\sqrt{s(s-a)(s-b)(s-c)}$

s= semi-perimeter $=\frac{a+b+c}{2}$

Given that , first angle is twice the second angle, and the second angle is 30° larger than the third angle.

Consider the second angle of the triangle be x.

Then first angle = twice the second angle

=2× second angle

=2x

The third angle+30° = second angle

⇒third angle= second angle -30°

= x- 30°

We know that,

First angle + second angle+ Third angle = 180°

⇒2x+x+x-30°= 180°

⇒4x = 180° +30°

⇒4x=210°

$\Rightarrow x= \frac{210^\circ}{4}$

⇒x=52.5°

Therefore the angles of the triangle are 52.5°, (2×52.5°),(52.5°-30°)

=52.5°, 105°,49.5°
