Answer:
124.5
Step-by-step explanation:
All you need to do is multiply.
15*8.3=124.5
This is because The total water in Ari's fish tank has 15 gallons, and each gallon has 8.3, so you multiply.
Answer:
65/72
Step-by-step explanation:
Given that ∠T=90° then the triangle ΔRST is a right angled triangle. Considering ∠S, RT is the opposite side, TS is the adjacent side and RS is the hypotenuse side. Using the notation
SOH CAH TOA
Tan ∠S = 72/65
Hence the cotangent of ∠S which is the inverse of the tangent will be
= 65/72
The correct answer would be :
<span>complementary angles
adjacent angles.

Answer:
Step-by-step explanation:
<u>Given equation</u>
<u>Solving for x</u>
- 5x - 2x = 2x - 2x
- 3x = 0
- 3x/3 = 0/3
- x = 0
<u>Let's see what the division method gives</u>
- 5x = 2x
- 5x/2x = 2x/2x
- 2.5 = 1, which is impossible
No solution. This method proves to be incorrect.
