Answer: Option B

Detailed Explanation:

In the figure in Option B, we are given 2 corresponding angles as equal in both triangles. We are also given one corresponding sides as equal.
Therefore, we can prove the congruency by AAS (Angle-Angle-Side).

Solve for X<br> 1. -5 = x - (-6)<br> 2. - 30=1.25x<br> 3. -6x=72<br> 4. -4.9=0.7x<br> 5. 3.15=0.45x
Hoochie [10]

Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7


Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.

-5 = x - (-6)

-5=x+6

Then subtract 6 from both sides.

-5=x+6

-11=x

The answer to the second can be found simply by dividing both sides by 1.25.

- 30=1.25x

-30/1.25=1.25x/1.25

24=x

The third one can be solved by as we said before dividing both sides by -6.

-6x=72

-6x/-6=72/-6

x=-12

The fourth one can be found again by using division on both sides.

-4.9=0.7x

-4.9/0.7=0.7x/0.7

-7=x

Finally we solve the last one by again doing the same thing dividing both sides by 0.45.

3.15=0.45x

3.15/0.45=0.45x/0.45

7=x

Hope this helps!

Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7). Which of the following expressions will he us
Masteriza [31]
Barry will use the distance formula:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(4 - 3)² + (7 - 1)²]
d = 6.08 units

Find the perimeter of ABC wirh vertices A(0,2) B(0,5) C( -6,2)
maxonik [38]

Answer:   \bold{9+3\sqrt{5}}

<u>Step-by-step explanation:</u>

Perimeter is the sum of the sides.

The length of AB is 3. The length of AC is 6. The length of BC can be found by using the Pythagorean Theorem: a² + b² = c²

3² + 6² = BC²

9 + 36 = BC²

45 = BC²

√45 = BC

3√5 = BC

Perimeter = AB + AC + BC

                 =  3  +   6  + 3√5

                 = 9 + 3√5
