Answer:
a) UT= 42
b) WT= 21
c) ST= 42
d) m<XT= 90
e) m<ST= 112
f) m<US= 85
Explanation:
In the given data, SV= 21. In the graph, measurement of WT is is equal to SV so the value of WT is also 21, while UT and ST both are double in length of SV , so we take double value of SV i. e. 42 for both UT and ST. In the given graph, the angle of UT is 112 degrees. If you see the graph, angle of ST is same to the m<UT, so we can write m<ST= 112. Line X and T are perpendicular to each other so they make right angled triangle i. e. 90 degree while line U and S is slightly inside which make the angle about 85 degree.
