1 answer:
Lyrx [107]4 years ago

Answer:

No.

Step-by-step explanation:

You have to imagine (or create a physical model so you can see) that the left and right frame pieces are joined to the top frame piece. The angle each "vertical" piece makes with the horizontal is the sum of the angles shown at each corner: 37° + 50° = 87°.

The angles at each of the corners constitute same-side interior angles where the horizontal transversal crosses the "vertical" lines of each of the side pieces. If the side pieces were parallel, those angles would be supplementary (add to 180°). Instead, they add to 87° + 87° = 174° ≠ 180°. Hence the "verticals" are <em>not parallel</em>.

_____

Usually, a "square" frame has right-angle corners. Here, the corner angles add to 87°, a few degrees short of a right angle. The effect will be to make the side pieces closer together at the bottom than they are at the top. (Parallel lines are the same distance apart everywhere.)

An angle measured 140 more than the measure of its supplementary angle. What is the measure of each angle ?
BARSIC [14]

Answer:

Supplementary angle equals 180°  

Complementary angle equals 360°

Step-by-step explanation:

Conjugate angles are more or less related to complementary and supplementary angles. The sum of the two angles put together equals 360 degrees. The last angle that will be named is straight. The measure of the angle equals 180 degrees.

Which expression can be used to find the surface area of the following rectangular prism? Choose 1 answer: (Choice A) A 15+15+10
xxMikexx [17]

Answer: A

Step-by-step explanation:

The rectangular prism has 6 faces  and to find the area of the faces we need to multiply the length by the width.  

the first face is: 3*2 = 6

Second face is:  3*2 =6

third face   js :  5*3= 15

fourth face is :  5*3 = 15

fifth face   is  :  5 * 2 = 10

sixth face  is :   5*2 = 10  

Now add them up

15 + 15 + 10 + 10 + 6 + 6  so A is the answer.

I=interst

P=2000
r=0.04
T=7

I=2000*0.04*7
I=560

2000+560=2560

you can buy something that costs $2560
