<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>
Using the formula
L=rx (x=angle)
x=L/r
x=8/3
x=2.6 radians
Answer:
The correct option is (C) (2.769, 3.231).
Step-by-step explanation:
The confidence interval for mean when the standard deviation is not known is:
Given:
Compute the critical value as follows:
**Use a <em>t</em>-table.
The 95% confidence interval for true mean length of the bolt is:
Thus, the 95% confidence interval for true mean length of the bolt is (2.769, 3.231).
The correct option is (C).
Find the slope of A. The slope of a line parallel to A would have the same slope of A. Remember, slope=rise over run.
