You make use of the relationships between angles in a circle, and the relationships between angles in a triangle. You are expected to know or have ready reference to the necessary relationships.

Upper Left.
.. x is the base angle of an isosceles triangle whose apex angle is twice 63°.
.. x = 27°

Upper Right.
.. x is supplementary to 73°.
.. x = 107°

Lower Left.
.. x is complementary to 50°.
.. x = 40°

Lower Right.
.. x is supplementary to twice the angle partially shown at the right side of the image. (The central angle between the radii to the tangent points is twice the angle partially shown. The angle to the radius at each point of tangency is 90°, and the sum of the 4 angles in the quadrilateral is 360°. Hence the relationship described in the first sentence.)

Please helppp
Roman55 [17]

Answer:

Step-by-step explanation:

To copy an angle we follow the following steps,

1). Draw a working line with the help of a straightedge.

2). Now we put a point S as the vertex of the angle.

3). Construct an arc with a radius 'r' (any length ) from vertex S which intersects the working line say at V.

4). With the same radius we draw an arc from point E which intersects the line ED and EF at G and H respectively.

5). Mark an arc from point G which intersects line EF at I.

6). Measure the distance between points G and I with compass and mark an arc from point V which intersects the previous arc say at U.

7). Now join the points S and U.

Hence we copy any angle.

The top of the desk is shaped like a trapezoid the bases of the trapezoid are 26.5 and 30 cm long the area of the desk is 791 CM
kotegsom [21]

Answer:

28 cm

Step-by-step explanation:

Given that :

Area = 791 cm

Base, b1 = 26.5 cm

Base, b2 = 30 cm

Area, A of trapezoid :

A = 1/2 (a + b) h

Where a and b are the bases ;

791 = 1/2(26.5 + 30)h

791 = 0.5(56.5)h

791 = 28.25h

h = 791 / 28.25

h = 28 cm

djverab [1.8K]

Answer:

102

Step-by-step explanation:

Paula's parents bought 102 mini-sandwiches. When I multiplied 17 by 6, I got 102. To check my answer, I divided 102 by 6 and got 17.

17x6=102

102/6=17

Hope this helps:)
