Answer:

$210 \: \: \: degrees$

Step-by-step explanation:

Two equilateral triangles and a square are join together.

So, in a equilateral triangle all the angles are equal. which means an angle measures 60 degrees.

Also in a square all the angles are equal . it measures 90 degrees.

x = two triangle = 60 +60

square = 90

$60 + 60 + 90 \\ = 210$

hope this helps you. 

brainliest appreciated 

good luck! have a nice day!

Solve the right triangle shown in the figure BC = 1.6in< A=48.8 C =90

yKpoI14uk [10]

Drawing a diagram to represent the information you've given, the only angle we are missing is B. We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
m∠B = 41.2°.
We can use the angles and the one side we're given to find the remaining sides. Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine. We must use tangent (the ratio for tangent is opposite/adjacent):
$\tan 41.2 = \frac{x}{1.6}$
Multiply both sides by 1.6:
$1.6 \tan 41.2 = x
\\ 3.67 = x$
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
$(1.6)^2+(3.67)^2=c^2
\\ 2.56+13.4689=c^2
\\ 16.0289=c^2
\\ \sqrt{16.0289} = \sqrt{c^2}
\\ 4=c$
The length of side AC, the hypotenuse, is 4 inches.
