What is the measure of this angle? Choose the best - 1

Answers

Answer 1
Answer:

Answer: 135°

Step-by-step explanation:

       We see that this angle looks to be greater than 90°. A 90°-angle is like one corner of a square. Since this angle is greater than 90 degrees, we can estimate the angle is 135° since it's the only one greater than 90° because 90° > 60° > 30°.

What is the intersection of plane STXW and SVUT?A. SV
B. ST
C. YZ
D. TX

Answers

B. ST is the intersection of plane STXW and SVUT.

Answer: B. ST.


Step-by-step explanation: The intersection of two planes, if exists, is a straight line. Since the planes STXW and SVUT have S and T as common points and we can always draw a straight line given any two points in a plane, so ST is the line joining the points S and T, and hence, it is the intersection of the two given planes.

Thus, the correct option is B. ST.
