DedPeter [7]

Answer:

In the given figure, line segment is constructed on the triangle parallel to line segment . ... This line can then be considered as a transversal of these parallel lines. Angle and angle are therefore corresponding angles. And as they're corresponding, this means that they're equal.

PLS SOMEONE HELP ME ASAP
babymother [125]

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

I need help answering this question.
Usimov [2.4K]

Answer:

28 degrees

Step-by-step explanation:

Since the lines are parallel this means that angle BEF and angle ABE are equal because they are alternate interior angles. We are given a right angle which measures 90°. This means we can do 118°-90° to give us angle ABD. This means that angle ABD is 28°.

Write the equation of a line whose slope is 2/3 and crosses the y axis at (0, -5)
postnew [5]

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=\frac{2}{3}x-5

Step-by-step explanation:

We will use the slope intercept form of the equation to make an equation of the given line

The slope-intercept form is:

y=mx+b

Here m is the slope and b is the y-intercept

Given

m = 2/3

Putting the value of slope

y=\frac{2}{3}x+b

The y intercept is -5 so we will put in the equation

y=\frac{2}{3}x-5

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=\frac{2}{3}x-5

Keywords: Equation of line, slope-intercept form
