In triangle JKL, if m

romanna [79]

Answer:

$\angle L = 52\\\\\angle J = 45\\\\\angle K = 83$

Step-by-step explanation:

$\angle J = \angle L-7\\\\\angle K=2\angle L-21\\\\\angle L = \angle L$

we know that

$\angle K +\angle J + \angle L =180$ by the sum of interior angles of a triangle

so we have

$(\angle L -7)+(2\angle L -21)+(\angle L)=180$

we can simplify

$(\angle L + 2\angle L + \angle L)+(-7-21)=180\\\\4\angle L -28=180\\\\4\angle L=180+28\\\\4\angle L = 208\\\\\angle L = 52$

and now we find the other angles

$\angle J = \angle L -7\\\\=52-7\\\\=45$

$\angle K = 2\angle L -21\\\\=2(52)-21\\\\=104-21\\\\=83$

Solve for x . Round to the nearest tenth, if necessary.

Jet001 [13]

Answer:

x = 24.1

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan 15 = x/90

90 tan 15 =x

x=24.11542

To the nearest tenth

x = 24.1

1. Find the volume of the rectangular prism.<br> 4 ft<br> 6 ft<br> 8 ft

ladessa [460]

Answer:

192 $feet^3$

Step-by-step explanation:

The formula for the area of a rectangle is : $length*width$

In order to work out the volume you would first need to work out the area. You can do this by multiplying the length of 6 by the height of 4, this gives you 24.

To workout the volume you would need to multiply the area of 24 by the width of 8, this gives you 192.

1) Multiply 6 by 4.

$6*4=24$

2) Multiply 24 by 8.

$24*8=192 feet^3$
