Answer:

you can use similar triangle to make known degrees in problems to make then easier to solve. With similar triangle, the angles are the same, but the scale is different. So by using this, one can solve both at the same time, and just just scale up the smaller one or scale down the larger, by the given/found scale.

Step-by-step explanation:

Answer:

You can indirectly determine the measure or size of something that is tedious to measure by hand.

Or by knowing that the triangles are similar, you can find the corresponding sides, angles or even other variables based on the information that is given.

If a triangle is similar to another, they are proportional; usually have congruent angles, which means that the only differing variable is the scale factor, or relative position.

Find m∠U.<br> Write your answer as an integer or as a decimal rounded to the nearest tenth.

Ilia_Sergeevich [38]

Answer:

∠U = 56.4

Step-by-step explanation:

We can use trigonometric functions to solve this

Here we are given the opposite side of ∠U as well as the adjacent side.

When dealing with the adjacent and opposite side we use sin

Sin = Opposite side / Adjacent side

Opp = 5 and adj = 6

Sin(U) = 5/6

* take the inverse sine of both sides *

arc(sin)(u) = u

arcsin(5/6) = 56.4 *( rounded to the nearest tenth )

∠U = 56.4

1. Over 3 years, how much more does $3000 in a savings account with an APR of 3.2% compounded

Sedbober [7]

Answer:

$1080

Step-by-step explanation:

$((3000 \times 0.032) \times 2) \times 3 = 576$

convert % to decimal by multiplying 3.2%x100=0.032

then multiply by initial amount 3000x0.032

then multiply by 2 because it's compounding semiannual

then multiply by 3 because it's over a 3 yr period

do the same for the quarterly compound but multiply by 4 because it's quarterly

$((3000 \times 0.03) \times 2) \times3 = 1080$

over a 3 yr period the quarterly compounded amount will earn:

$1080 - 576 = 504$

$504 more than the account compounded semiannual

The slope of the line below is -5. Which of the following is the point slope form of the line (2,-7)

Dominik [7]

Equation of the line in point slope form is y + 7 = -5(x - 2)

Step-by-step explanation:

Step 1: Given slope of the line is -5 and passes through the point (x1, y1) = (2,-7). Equation in point slope form is y - y1 = m(x - x1)

⇒ y - (-7) = -5(x - 2)

⇒ y + 7 = -5(x - 2)
