Answer:
∠SVU = 49°
Step-by-step explanation:
∠SVU is an inscribed angle and arc SU is the arc it intercepts
If you didn't know an inscribed angle is equal to half the measure of its intercepted arc.
Hence ∠SVU = arc SU / 2
if arc SU = 98
Then ∠SVU = 98/2 = 49
7) x = 12 and the side lengths are all 23
9) x=19, AB=BC=98, AC=125
10) x=14, GI=HI=39, GH=17
Answer:
∠ 1 = ∠ 2 = 75°
Step-by-step explanation:
The sum of the 3 angles in Δ CDE = 180°
sum the angles and equate to 180°
∠ 1 + 38° + 67° = 180°
∠ 1 + 105° = 180° ( subtract 105° from both sides )
∠ 1 = 75°
∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so
∠ 2 = 75°
Answer:
Quadrants I and II.
O: (-2, 2)
N: (-2, 4)
M: (1, 4)
P: (1, 2)
Step-by-step explanation:
When rotating about the origin 90 degrees in a counterclockwise direction, focus on the coordinates of one point on the preimage at a time. So, the x-coordinate on the image will be the opposite of the y-coordinate of the preimage, and the y coordinate of the image will be the x-coordinate of the preimage. That sounds complicated so here is an example from the problem.
O is a point on the preimage. Its coordinates are (2, 2). To find the x-coordinate, take the opposite of the image's y-coordinate. The y-coordinate is 2, so it will be a -2 x-coordinate on the image. To find the y-coordinate on the image, take the x-coordinate of the preimage (O). The x-coordinate of O is 2, so the y-coordinate of the image will be 2. Combine those together and after a 90 degree counterclockwise rotation, you get a point of (-2, 2)
