Answer:
b+24
x-18
a/3
Step-by-step explanation:
Answer: y = 0.5, x = 50
Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:
a triangle has 180 degrees so we subtract the given 50 which gives us 130
2(2y + 64) = 130
4y + 128 = 130
y = .5
This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:
2(45 - x/4) = 65
x = 50
This means the bottom 2 angles of the second triangle are both 32.5.
64, because its square root is 8.
49, because its square root is 7.
144, because its square root is 12.
4, because its square root is 2.
Answer:
Step-by-step explanation:
(a). B, C and D are the distinct points that are collinear.
(b). FC and BD are the distinct lines that intersect each other at a point C.
(c). E, F, C and A are the points that are coplanar (on the same plane).
(d). Another name for plane X is plane AEF. (Since a plane is defined by the three distinct points on the same plane.
