In Quadrant IV, x is positive and y is negative
When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (this can only be used for RIGHT triangles)
Pythagorean Theorem:
a² + b² = c² [c is the hypotenuse, or the longest line]
Since you know b = 8 and c = √73, plug it into the equation
a² + 8² = (√73)²
a² + 64 = 73
a² = 9
a = √9
a = 3
2.00 - 1.50 = 0.50
0.50 - 1.75 = -1.25
Solution: he owns $1.25
Answer:
y = 23
x = 28
Step-by-step explanation:
Find y first.
3y + 5y - 4 = 180 The two angles are supplementary if the all the lines are parallel. Combine the left side.
8y - 4 = 180 Add 4 to both sides
8y - 4 + 4 = 180 + 4
8y = 184 Divide both sides by 8
y = 23
====================================
Now if the lines are parallel, then 3y = 2x + 13
But we already know y
3*23 = 2x + 13 Do the multiplication
69 = 2x + 13 Subtract 13
56 = 2x Divide by 2
x = 56/2
x = 28
Answer:
7/10 x 3/6 = 21/60
21/60 in its simpliest form = 7/20
