Answer:
x = 105 degrees
Step-by-step explanation:
First, figure out the interior angle, we can do this ading the two angles and then subtracting the sum from 180 (since the interior angle of a triangle adds up to 180 degrees)
180 - (55 + 50) = 75
next, we can figure out x by taking the sum (75) and subtracting that from 180 since it is a supplementary angle:
180 - 75 = 105
x = 105
834+14s=848>978-10s=968
a real life situation for that could be like how many apples 848apples/968total
Answer:
-x +8
Step-by-step explanation:
3x + 6 + -4x + 2
Combine like terms
3x-4x +6+2
-x +8
It’s a square so it means you have to multiply 7*7*2.75 to get 134.75
Multiply that by 7.5 because one cubic foot holds 7.5 gallons
1010.625 *.03 since its 3 cents per gallon
30.318
Round up
$30.32 is the answer
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
