Answer:
Angle 1 is 58. Angle 2 is 32.
Step-by-step explanation:
The measure of Angle ACB is 90 because C is on the circle and A and B connect to form a diameter of the circle. So, Angle 1 and Angle 2 add up to 90 (total degrees in triangle - 90). Now you can add the expressions the question gave for Angle 1 and Angle 2, and you get 7x + 6. So you have the equation 7x + 6 = 90. Solve the equation and you get x = 12. Now you can plug in that value for x into the expressions for Angles 1 and 2 to find their measures.
Answer:
8 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , that is
exterior angle + 135° = 180° ( subtract 135° from both sides )
exterior angle = 45°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular then number of sides n is
n = 360° ÷ 45÷ = 8
Answer:
D.angle
Step-by-step explanation:
If two rays have the same endpoint, then they do not necessarily have to be opposite rays. They could form an angle instead.
Hello,
Here i am using vectors
==> AB//DC and AD//BC (definition of a translation)
The quadrilater ABCD is a parallelogram:
so
1) his diagonals have the same length;
2) his diagonals are cutting in the middle.
(these are proprieties of a parallelogram)
D. 140 cm, because 5 x 4=20 and 20 x 7 is 140.
