Hi there!

We can find the area of a triangle with the formula:
area = 0.5 \times base \times height

Filling in this formula gives us the following answers.

Triangle 1
area = 0.5 \times 5 \times 8 = 20

Triangle 2
area = 0.5 \times 7 \times 9 = 31.5

Triangle 3
area = 0.5 \times 16 \times 12 = 96

A=bh divided by 2!!

1. A=1/2(8)(5)
So A equals: 20.

2. A=1/2(9)(7)
So A equals: 31.5.

3. A=1/2(16)(12)
So A equals: 96.

Hope this helps!

Calculate the distance between the points (-1, 3) and (4, -1).
BigorU [14]

The distance between those two points is 41 and in decimal form to the nearest tenth, that's 6.4

Explanation:

Use the distance formula: √(x2 - x1)² + (y2 - y1)²

Then we plug in our x's and y's:

√(4 - (-1))² + ((-1) - 3)²

Then you simplify:

√(5)² + (-4)²   = √25 + 16

√41 (And if you need to, you can put this into decimal form.)

love history [14]

Answer:

3. i think 15.5

4. 140*

Step-by-step explanation:

in number 4, d is a vertical angle to the angle measured at 140.

in number 3, QV=SV, so 17=4x-1     18=4x    18/4=x   x=4.5

and TS=TQ, so 3(x) + 2 = 3(4.5) + 2 = 13.5 + 2 = 15.5 =TQ

Which of the following pairs of angles are congruent? ( Answer as soon as possible)
Aleks04 [339]

Answer:

C. <w and <y

Step-by-step explanation:

<t and <x are corresponding angles, therefore they are congruent to each other by the corresponding angles theorem.

<w and <y are also corresponding angles and are therefore also congruent.

<x and <z are congruent also based on the vertical angles theorem.

<t and <z are alternate exterior angle, and are therefore congruent also.

So, from the pairs of angles given as options, the only given pair of angles that are congruent would be:

<w and <y
