Answer:

x= 145 degrees

Step-by-step explanation:

I'm going to assume that the 2 lines are parallel only because if they weren't, the problem would be impossible to solve.

If 2 parallel lines are cut by a transversal, then:

1. Corresponding angles are congruent

2. Alternate interior angles are congruent

3. Alternate exterior angles are congruent

4. Consecutive interior angles are supplementary

So, how do you solve this?

There are many ways.

1. All vertical angles are congruent. In this case, x and a 145 degree angle is congruent. This is one way to show x=145

2. x and another 35 degree angle are consecutive interior angles. They should add up to 180 degrees, 180-35-145. Therefore x=145 degrees.

The area of Sahara desert is 7 times the area of the Gobi Desert. If the sum of their areas is 4,000,000 square miles, find the

ryzh [129]

X=area of Sahara.
y=area of the Gobi Desert.
We suggest this system equations:
x+y=4000000
x=7y
solve by susbstitution method.
(7y)+y=4,000,000
8y=4,000,000
y=4,000,000 / 8=500,000

x=7y
x=7(500,000)=3,500,000

The area of Sahara=3,500,00 miles².
The area of the Gobi Desert=500,000 miles²

To check:
Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles²
Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).

What diretction does the parabola open if its equatin is y=-4(x+2)^2

Fed [463]

It is a cap-size parabola. The parabola "goes down". The graph of this function looks like in this attached picture.
