How do I find the missing sides in this triangle?

stiv31 [10]

Answer:

This is a 30-60-90 triangle so you would do this formula:

Short side (opposite the 30 degree angle) = x.

Hypotenuse (opposite the 90 degree angle) = 2x.

Long side (opposite the 60 degree angle) = x√3.

Helpppp meeeee outttttt pleaseeeee ASAPPPP!!!!

Answer:

$\boxed{\sf sin\ C =\frac{40}{41}}$

Step-by-step explanation:

We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .

We know that the ratio of sine is perpendicular to hypontenuse .

$\sf\longrightarrow sin\theta =\dfrac{ perpendicular}{hypontenuse}$

Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,

$\sf\longrightarrow sinC =\dfrac{ p}{h}\\\\\sf\longrightarrow sin\ C =\dfrac{AB}{AC}$

Substitute the respective values ,

$\sf\longrightarrow \boxed{\blue{\sf sin\ C =\dfrac{40}{41}}}$

<u>Hence the required answer is 40/41.</u>

Please please help me in these questions

a. a=40° (alternate interior angles)

b+40°=180°( supplementary angles)

b=140°

c= d= 140°( vertically opposite angles)

d=b=140°( corresponding angles)

b. 2a+120°=180° (supplementary angles)

2a=60°

a=30°

c. a+110°=180°( supplementary angles)

a=70°

b+70°=180°( supplementary angles)

b=110°

c+110°=180°( supplementary angles)

c=70°

c=d=70( corresponding angles)
