First you have to subtract 35 on both sides, then you would have to divide by 90
(b) is the answer.
Step-by-step explanation:
By the Pythagorean Theorem,
A² + B² = C²
Where:
A = Length of side 1
B = Length of side 2
C = Hypotenuse
This rule applies to all right-angled triangles.
The length of the hypotenuse of a right-angled triangle is always the largest value.
Therefore, we can test the answers with the equation above.
(a)
8² + 18² = 20²
64 + 324 = 400
388 ≠ 400
The rule of Pythagorean theorem doesn't work on a, so (a) is not a right-angled triangle.
(b)
12² + 35² = 37²
144 + 1225 = 1369
1369 = 1369
The rule of Pythagorean theorem works here, so (b) is a right-angled triangle.
Answer:

Step-by-step explanation:
Answer:
36%
Step-by-step explanation:
line up $ and % data like this:
$2.79 represents 100%
$3.79 represents X%
cross multiply
X*2.79 = 3.79*100
divide both sides by 2.79
X= 3.79*100 / 2.79 ≈ 136%
so it increased 36%
Answer:
Step-by-step explanation:
I believe this is the correct answer. In order to check that my equations are correct I put in some dummy numbers.
a= 2
b=4
c=
