<span>So, they are looking for the percentage that is NOT explained...
Well, given the r we can find the percentage that IS explained by it first. That's given by r^2.
</span>Now - let's take the square of r it gives me .481636. That means that about 48% IS explained. Therefore, the part that cannot be explained
must be the missing part (out of 100% <span>so
100% - 48.1636% should be it :)
</span>
<span>So 100% - 48.1636% = 0.518364 and we want to round that off to three decimal places which will give us 0.518... and then we could convert that to a percent for the final. So 0.518 as a percentage is 51.8%! s</span>
Answer:
true and true
Step-by-step explanation:
i took the test
we know that
Two angles are supplementary if their sum is equal to
degrees
in this problem we have


so
therefore
<u>the answer is</u>
The two angles are supplementary
<h3>Answer: angle T = 70</h3>
======================================
Work Shown:
Quadrilateral RSTU is a kite. In geometry, any kite has two pairs of adjacent congruent sides. In this case, RU = RS is one pair of adjacent congruent sides (single tickmarks), while TU = TS is the other pair of adjacent congruent sides (double tickmarks).
Draw diagonal line segment TR. This forms triangles TUR and TSR.
Through the SSS (side side side) congruence theorem, we can prove that the two triangles TUR and TSR are congruent.
Then by CPCTC (corresponding parts of congruent triangles are congruent), we can say,
angle U = angle S = 90
--------------
Re-focus back on quadrilateral RSTU (ignore or erase line segment TR). The four angles of any quadrilateral will always add to 360 degrees. Let x be the measure of angle T.
(angleU)+(angleR)+(angleS)+(angleT) = 360
90+110+90+x = 360
290+x = 360
290+x-290 = 360-290 ... subtract 290 from both sides
x = 70
<h3>angle T = 70</h3>
