Find the measure of the given angles

Answers

Hey there!

The answer is 58 degrees

Since ΔABC ~ ΔDEF, then m∠A ~ m∠D, and m∠B ~ m∠E, and m∠C ~ m∠F. This means we can set m∠A equal to m∠D:

x + 29 = 2x

Subtract x from both sides:

29 = x

Now, we plug into the angle expressions to find their measurement:

m∠A = 29 + 29

m∠A = 58

Since they are equal, m∠A and m∠D are both 58 degrees.

what is 11/4-3/8= what is it or get me the right answer

Answers

Answer:

2 3/8 is the answer

Step-by-step explanation:

11/4 - 3/8

We will find the LCM of 4 and 8, which is 8.

We will do 11/4*8, which 8/4 = 2 and 2*11 = 22

Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3

So the answer will be 22-3 =  19

                                        8     =   8

During a pie eating contest, a person ate 12 pies in 60 minutes. How many pies did the person eat per minute? Group of answer choices

Answers

Answer:

5 per minute

Step-by-step explanation:

Answer:

The person ate 5 pies per minute

Step-by-step explanation:

If 12 pies were eaten in 60 minutes , you must divide the denominator (60) by 1 (the per minute). Whatever you do to the bottom, you must do to the top, so 60 / 12 is 5.

Triangle MAT is isosceles, angle A is the vertex angle, AT = 8x-3, MT = 2x+3 and MA=5x+15. Find the value of x and the indicated measures.

Please solve step by step to help me understand. Thanks!

Answers

Answer:

x=6, AT=45, MT=15,  MA=45

Because it is isosceles, MA=AT, so 8x-3=5x+15, solve for x and then plug it into the equations.

two numbers have ratio 12:5.their differnce is 49.find the two numbers .​

Answers

Answer:

84 and 35

Step-by-step explanation:

12 - 5 = 7

12(7) = 84

5(7) = 35

Two numbers: 84 and 35

Step-by-step explanation:

Let the two numbers be x and y

Given:

Ratio of two numbers= 12:5

Difference between two numbers= 49

So, we need to find the difference between its ratio in order to get two numbers.

12 - 5 = 7

Thus, simply on multiplying the number so obtained after subtraction we will get:  

12 * (7) = 84

5 * (7) = 35

Also, the difference is given which is 49

so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49

Therefore, the two numbers are 84 and 35.
