Answer:
No
Step-by-step explanation:
2x+5.2 + 3x+ 1.2 +2x+6.2= 180
7x+ 12.6=180
7x 12.6 - 12.6=180 -12.6
7x = 167.4
x = 23.914
should equal 60
Answer:
the slope that is perpendicular to line y=-7x-12 is 1/7
1/7 is the perpendicular slope
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
Answer:
x = <u>16</u> units
Step-by-step explanation:
∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.
If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.
Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.
Since side BC is part of BCD.
Side opposite of 90° [∆BCD] = BC = 32.
Since x is opposite of 30° [∆BCD].
x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
