Answer:

I need more info about the shape were making but I think C is the answer.

Step-by-step explanation:

I'll be honest Im confused. Im going to assume your finding the third side of triangle and if so here is my answer.

Side GH must be between 3.5 and 23.1 not inclusive because 13.3+9.8= 23.1 and that would be the length if the line is a straight line, and the minimum is 13.3-9.8= 3.5 and that is only if the lines overlap. That only leaves C as the answer within the range.

Us<br> Find the area shaded in yellow.<br> [ ? ] square units

ira [324]

Answer:

45 square units

Step-by-step explanation:

You can cut the yellow figure into a triangle (4 by 5) and a rectangle (7 by 5).

Using the formula $\frac{1}{2} *b*h$ and $l*w$ area formulas, we get:

$\frac{1}{2} *4*5+7*5=\\2*5+7*5=\\10+35=\\45$

The area shaded in yellow is 45 square units

If angles A and B are consecutive interior angles, what is the measure of

n200080 [17]

Answer:

A. 105°

Step-by-step explanation:

Consecutive interior angles are angles that are supplementary, meaning they add up to 180°. If one angle is worth 75°, to find the other angle, we subtract 75 from 180 to get the angle measure.

$180-75$
$105$

Therefore, the answer is A.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Solve a triangle when A=15° B=113° and b=7?

JulsSmile [24]

Let us draw a triangle ABC with A=15° ,B=113° and b=7.

Please see the attached image.

We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have

$A+B+C=180\\
\\
15+113+C= 180\\
\\
C=62^{\circ}$

Apply Sine rule in the triangle ABC, we get

$\frac{a}{\sin 15}= \frac{7}{\sin 113}\\
\\
a=\frac{7 \sin 15}{\sin 113}\\
\\
a=1.97\\
\\
\text{Again apply sine rule, we get}\\
\\
\frac{c}{\sin 62}= \frac{7}{\sin 113}\\
\\
c=\frac{7 \sin 62}{\sin 113}\\
\\
c=6.71$

Therefore, we have

$a=1.97\\
c=6.71\\
C=62^{\circ}$
