Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
A trapezium is a quadrilateral. The option that is true for the trapezium is A, D, and E.
<h3>What is Trapezium?</h3>
A trapezium is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.
The given trapezium is an isoceles trapezium. Therefore, the properties of the trapezium that are true for KLMJ are:
- KL is parallel to JM
- ∠J is supplementary ∠K
- ∠J is congruent to ∠M (Valid only for isoceles trapezium).
Hence, the option that is true for the trapezium is A, D, and E.
