Answer = –3/2
Use rise/run to find the gradient, while finding the difference between the two points.
Equation of slope:
y2 - y1 / x2 - x1
-1-2 / 3-1
–3/ 2
Slope = –3/2

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cosθ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = C
Adjacent Leg = 10
Hypotenuse = 26
<u>Step 2: Find ratio</u>
- Substitute [cosine]: cos∠C = 10/26
- [Fraction] Simplify: cos∠C = 5/13
Answer:
14.8
Step-by-step explanation:
If you are allowed a calculator, the formula to find the percentage is found by multiplying the percentage by the whole number. For example, when you put in the calculator, 18.5% x 80= 14.8
14.8 being your answer. I hoped this helped!
One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
