Answer:

A=674.5cm square

Step-by-step explanation:

First, using pythagoras theorem:

Cos x =2/5-90=66.4

This is angle ACD.

Then 1/2 absinC=1/2(5x4)sin66.4

=664.2cm square

Next, find angle DCB by 90-23.578=66.4

And angle CBD by 180-30-66.4=23.578

Use sin23.578=4.58/H

H=11.45cm(length of d)

Now, use 1/2absinC again to find the area of another part of the triangle.

1/2 11.45x4.5sin23.6=10.31cm square

Lastly add them up!

A=664.2-10.31cm =674.5cm square.

What kind of angles are they
Yuliya22 [10]

Answer:

Alternate Interior Angles

Step-by-step explanation:

The angles are on opposite sides of the transversal and are in between the parallel lines. This means they are alternate Interior Angles. Additionally, this means they are congruent, so 15x=12x+15, which gives us x=5, and the measurements of the angles are 75° each.

Find the equation (in terms of x ) of the line through the points (-2,5) and (3,4)<br> y=
Alja [10]

Answer:

y = (-1/5)x + 23/5

Step-by-step explanation:

Given:

Two points;

(-2,5) and (3,4)

Find:

Equation of slope

Computation:

y = mx + b

5 = m(-2) + b

5 = -2m + b .......... Eq1

4 = m(3) + b

4 = 3m + b .......... Eq2

Eq2 - Eq1

-1 = 5m

m = -1/5

5 = -2m + b

5 = -2(-1/5) + b

5 = 2/5 + b

b = 23/5

y = mx + b

y = (-1/5)x + 23/5
