$\huge\boxed{Hi\;there!}$

Remember, all angles in a triangle always add up to 180 degrees.

We are given two out of three angles. We are given the measure of one angle (50 degrees) and the measure of another angle (Right angles always equal 90 degrees)

So, we have an equation:

x+90+50=180

x=180-90-50

x=90-50

x=40

$\huge\boxed{Answer:40 \;degrees}$

$\huge\bold{Good\;luck! \;Hope\;my\;answer\;helps!}$

Answer:

40°

Step-by-step explanation:

Missing angle

= 180° - 90° - 50° (angle sum of triangle)

= 40°

By decomposing the figure in simpler shapes, we will see that the total area is:

a = 180 cm²

<h3>How to find the area of the composite figure?</h3>

Remember that the area of a rectangle of width W and length L is:

A = L*W

And the area of a triangle with base B and height H is:

A = B*H/2.

Then, the upper part can be seen as a rectangle of length of 6cm and width of 6 cm, with two triangles on the sides, such that each triangle has a base of 3cm and a height of 6cm.

So the area of that part is:

A = 6cm*6cm + 2*(3cm*6cm/2) = 54cm²

Now, the bottom triangle has a base of 12 cm, and a height of:

15cm - 6cm = 9cm

Then its area is:

A' = 12cm*9cm/2 = 54cm²

This means that the total area of the figure is:

total area = 54cm² + 54cm² = 108cm²
