Well, we can find c with the equation c^2=a^2+b^2
c^2=25^2+28^2 c^2=625+784 c^2=1409 square root both sides to isolate c. c=√1409 c=37.53664876

A = 58°
Tan B=b/a Tan B=28/25 Tan B=1.12 B=tan^-1(1.12) B=48.2397003° or B=48°

All triangles have a total of 180° internal angel measurements. 180°-58°-48°=74°
This works because angle C would be the largest angle anyways.

What is the value of z in the equation 2z + 8 = −6? −1 −7 1 7

vitfil [10]

Answer:

So the answer is -7

Step-by-step explanation:

2z + 8 = −6

2z + 8 -8 = -6 -8 ( add - 8 for both sides)

2z = -14

2z/2 = -14/2 (divide both sides by 2)

z = - 7

So the answer is -7

A line passes through (5,-2) with a slope of 1/4. Write the equation in slope-intercept form.

trapecia [35]

Answer: y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

Step-by-step explanation:

Slope-intercept form is in the form of y=mx + b where m is the slope and b is the y-intercept.

We are given the slope, so we will plug this in.

y = mx + b

y = ( $\frac{1}{4}$ )x + b

Now, we will solve for the y-intercept by plugging in the point they give us.

y = ( $\frac{1}{4}$ )x + b

(-2) = ( $\frac{1}{4}$ )(5) + b

-2 = 1.25 + b

-3 $\frac{1}{4}$ = b

Lastly, we will plug this variable into the equation we wrote above for our final answer.

y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

Jenna goes for a jog every morning. The line plot shows the number of hours she jog for 5 days how many total hours did she draw

vichka [17]

You need to show the line put. If you show the line plot i may be able to answer. But F.Y.I. you are going to probably using proportions or need to multiply the hours she jogs in one day by the 5 days. Hope this helps.
