What is the measure of angle 7?
gladu [14]

Answer: 95°

Step-by-step explanation: We are given information for Angles 1 and 4, which happen to be vertical angles, meaning they are congruent. Because of this, we can say 3x+10=4x-15, therefore x=25. Angles 1,2,3 and 4 must add up to 360°, and since we know angles 1 and 4 are 85° (3*25 + 10 = 85), we can find angles 2 and 3. 360° - 85° - 85° = Angle 2 + Angle 3. Angle 2 + Angle 3 = 190, and because Angles 2 and 3 are vertical angles and therefore congruent, we can divide 190 by 2 and get that Angles 2 and 3 equal 95°. Because lines b and c are parallel, any corresponding angles created by a transversal are congruent. This basically means Angles 3 and 7 must be congruent, therefore Angle 7 = 95°

Congruent - same meaning as equal

Vertical Angles - each of the pairs of opposite angles made by two intersecting lines.

The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1
mote1985 [20]

Answer:

(7x+3/4*[x-1])^2

Step-by-step explanation:

The square of the sum of 7 times x. and 3 divided by 4 times the difference of x and 1. This would mean that (7x+3/4*[x-1])^2 You would perform x - 1 in the [] first, which is why they are in the extra brackets. The whole thing is squared, so it is all in parenthesis, being squared. It says 3/4 into x-1. This would mean it's multiplying into x-1.
