2x-8=x+4. What would x be
CaHeK987 [17]

2x - 8 = x + 4

Collecting like terms,

2x - x = 4 + 8

Since the signs change when its position changes.

x = 8 + 4 \\ x = 12

URGENT GEOMETRY!!
Darina [25.2K]

Answer: 140 degrees

A straight line is 180 degrees. Since we know one of the angles in the line is 40, we just subtract 40 from 180. So, the measure of angle 1 plus the measure of angle 2 is 140 degrees.

Find the measure of two supplementary angles, ∠A and ∠B, if m∠A = (3x – 7)° and m∠B = (2x + 2)°. =180
nikklg [1K]

Answers:

Angle A = 104 degrees

Angle B = 76 degrees

=================================

Supplementary angles add to 180 degrees.

A+B = 180

(3x-7)+(2x+2) = 180

5x-5 = 180

5x-5+5 = 180+5 ... add 5 to both sides

5x = 185

5x/5 = 185/5 .... divide both sides by 5

x = 37

Use x =37 to find

Angle A = 3x-7 = 3*37-7 = 111-7 = 104 degrees

Angle B = 2x+2 = 2*37+2 = 74+2 = 76 degrees

As a check: A+B = 104+76 = 180 so that helps confirm the answer

Brian’s kite is flying above a field at the end of 65m of string. If the angle of elevation to the kite measures 70; how high is
REY [17]
If the height is h, then h/65=sin70, so h=65sin70=61.08m approx.
