The pair of figures is similar. Find X. Round to the nearest 10th if necessary.
Answers
Answer:
x = 9.775 cm ≈ 9.8 cm
Step-by-step explanation:
If traingles are similar, then corresponding sides are in proportion:
cross multiply
divide both sides by 40
Answer:
9.7 rounded to 10
Step-by-step explanation:
I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do , you would the cross multiply 23×17 and 40×X. You would then have 40X=391, so you would divide 391÷40, so X=9.7 or 10

Answer:
your answer depends on what sides are given.
For example, lets say that you now the lengths of two sides, these being 56 and 24. ( these are just random numbers BTW) to find the third you would add the two lengths that you know and then minus them from 180. So for the example i just typed you would do 56 + 24 first which equals 80, then would do 180-80 which equals 100.

Answer:
Use the Pythagorean Theorem: a² + b² = c².
Step-by-step explanation:
For any given right triangle the sum of the measures of the sides squared is equal to the hypotenuse squared. The formula is call the Pythagorean Theorem and is written: a² + b² = c², where 'a' and 'b' are the legs of the triangle and 'c' is the hypotenuse.
Depending on which side of the triangle they give you, you can plug the other two side lengths into the equation to solve for the third.

Answer: x= 41
Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.
You can check to make sure by plugging in x for 41 .
Hope this helps!

Answer:
The length is 65 cm and the width is 12 cm
Step-by-step explanation:
A = lw = 780
P = 2 (l+w) = 154
The length is 5 more than 5 times the width
l=5w+5
P = 2 (l+w) = 154
Divide each side by 2
2 /2 (l+w) = 154/2
l+w = 77
Substituting l = 5w+5
5w+5 +w = 77
6w+5 = 77
Subtract 5 from each side
6w +5-5 = 77-5
6w = 72
Divide each side by 6
6w/6 = 72/6
w = 12
Now lets find l
l = 5w+5
l = 5(12)+5
l = 60+5
l = 65
