1. The diagram shown is two intersecting lines. The measure of <5is 47°.
Savatey [412]

The measure of ∠7 is 47°. Angle 7 is a vertical angle to angle 5

Suppose the measure of ∠6 is represented represented by (2x - 5), the equation that can be use to solve for x is 42 + 2x = 180

The value of x is 69

<h3>Vertical opposite angles</h3>

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.

Vertical opposite angles are congruent. Therefore,

a. ∠5 ≅ ∠7 (vertical angles)

Therefore, angles 5 and 7 are congruent angles.

∠7 = 47°

b. Suppose ∠6 = 2x - 5 . let's find x

Therefore,

∠5 + ∠6 = 180(angle on a straight line)

The equation to solve the above is as follows:

47 + 2x - 5 = 180

42 + 2x = 180

2x = 180 - 42

2x = 138

x = 138 / 2

x = 69

You have a coupon for 10% off the sale price of a surfboard. which is the better buy? explain your reasoning. ● 40% off the regu
just olya [345]
40 percent off because if there is 100 percent minus 40 that's 60 percent then if our work out the other one as 100 minus 30 equals 70. 70 the sale price divided by 10 because that's how much you get off equals 7. 30 plus 7 equals 37 which means you would only get 37 percent off.
