Ok, so the set up would be 3x+8 = 5x-40. If you solve for x you can then enter it into the equation and get your answer.

So subtract 3x from 3x and 5x. That leaves you with 8 = 2x-40

Next, you add 40 to both sides leaving you with 48 = 2x

Now divide 2 from x and 48 which give x = 24

Enter the value of x into the equation 3x+8

3(24)+8

80

And because we know it is an acute angle, angle ABC = 80 degrees

Answer:

m<4=40

Step-by-step explanation:

Supplementary angles form 180 degrees

m<3 is vertical to the 50 degree angle which is equal.

so. m<3=50

m<5=90

90+50=140

180-140=40

m<4=40

PLEASE HELP ME!! LAST ASSIGNMENT
Darya [45]

Answer:

u = 3

Step-by-step explanation:

\frac{10}{14} = \frac{35}{u + 46} \\\\ 10(u + 46) = 35×14 \\\ 10u + 460 = 490 \\\ 10u = 490 - 460 \\\ 10u = 30 \\\ u = \frac{30}{10} \\\\ u = 3

I hope I've helped you.

!!!!!!!!HELP PLEASE!!!!!!!!       In ΔSTU, SU = 18 and TU = 13. Find m∠T to the nearest tenth of a degree.
tatyana61 [14]
We can use a trig function to find the measure of angle T.

tan(T) = 18/13

Take the archtangent on both sides since we are searching for an angle.

arctan(tan T) = arctan(18/13)

T = 54.16°

The measure of angle T is 54.16°.
