In triangle ABC find b to the nearest degree given a=7 b=10 and c is a right triangle

eimsori [14]

Answer:

∠B = $55.00797173^{\circ}$

Step-by-step explanation:

Given : a=7 b=10 and C is a right triangle

solution :

refer the attached figure .

Since ΔACB is right angled triangle so we will use trigonometric ratios .

$tan\theta=\frac{perpendicular}{base}$

Perpendicular = b =10

Base=a=7

Putting value in formula:

$tanB=\frac{10}{7}$

$tanB=1.42857$

$B=tan^{-1}1.42857$

$B=55.00797173^{\circ}$

Thus ∠B = $55.00797173^{\circ}$

Need help with this angle don't know what to do with the x

vichka [17]

Hello!

Due to the definition of the Alternate Interior Angles Theorem, (x+23)+(x+54)=180 degrees:

x + 23 + x + 54 = 180
2x + 77 = 180
2x = 103
x = approximately 52 degrees or exactly 51.5 degrees

I hope this helps :))
