PLS ANSWER ITS URGENT

Answer:

The length of the ramp must be at least 14.71 feet

Step-by-step explanation:

Given

$BC = 2.3ft$

$\theta = 9^\circ$

See attachment for complete figure

Required

Length of the ramp (z)

To do this, we consider sin of angle A ( $\theta$ ).

So, we have:

$sin\theta = \frac{Opposite}{Hypotenuse}$

This gives:

$sin(9)= \frac{2.3}{z}$

Make z the subject

$z= \frac{2.3}{sin(9)}$

$z = \frac{2.3}{0.1564}$

$z = 14.71 ft$

The length of the ramp must be at least 14.71 feet

(6y+4) = (3y+37) Find the measurement of angle G in the parallelogram EFGH.

IRINA_888 [86]

Yo sup??

The given figure is a parallelogram therefore opposite angles must be equal

6y+4=3y+37

3y=33

y=11

angle H =3*11+37

=70

angle G=180- angle H. (property of parallelogram)

=180-70

=110

Hope this helps
