Equal angles sweep out equal lengths in a triangle. The two legs - let's call them a and b - are each across from 45 degree angles, so we know that a = b, which means that their ratio, a:b, will be 1:1, since the ratio of any number to itself is 1:1.

Answer:

RECT and ANGL are similar triangles with a ratio of 9:16, and for TR, we have TR:24 in the ratio 9:16 so TR = 13.5

Hope this helps!

Triangle XYZ is reflected across the y-axis, and X = (4,-5). What are the coordinates of X’ ?
adelina 88 [10]
The correct answer is B.

You can come to this decision by picturing the initial point in your mind. Point X has a positive x-value and a negative y-value. This puts it in quadrant 2 on the coordinate plane. Now, if you flip that point over the y-axis, that makes its new location in quadrant three. In quadrant three, both the x and y coordinates are negative. So, the value wouldn’t change but both would become negatives.

I hope this helps. :)

inn [45]

Answer:

The sample size is 183.

Step-by-step explanation:

Given:

σ = $1050, ppulatin standard deviation

99% confidence interval

Accuracy = +/- $200

The accuracy is given by

z*(σ/√n)

where

z* = 2.576 for 99% confidence level (from tables)

n = sample size

Therefore

2.576(1050/√n) = 200

√n = (2.576*1050)/200 = 13.524

n = 182.9

<em>The sample size is 183</em>

Find the measure of the smallest angle?
weeeeeb [17]

Answer:

m ∠RMK = 51°

Step-by-step explanation:

m ∠JMK = m ∠RMK + m ∠JMR

10x + 19 = 7x - 26 + 6x + 12

10x +19 = 13x -14

19 = 3x -14

 33 = 3x

 11 = x

m ∠RMK = 7(11) - 26 = 51°

m ∠JMR = 6 (11) + 12 = 78
