Notice that based on the diagram, all of the sides of the triangle are the same length. (The dashes on the sides of the triangle show that the sides are of congruence.) This means that the triangle is an equilateral triangle. An important thing to note about equilateral triangles is that they all have angles of 60°. All angles in equivalent triangles are 60°.
This means that we can set
equal to 60 to solve for

Our answer is x = 9.
You write it as 46 divide by 1058. 46 x 2 is the closest you will get to 100. 46 x 2 is 92. put it in and you have 138 left. multiply 46 x 3 and you will get 138. amswer is 23. remember to bring down the next number whwn dividing
Answer:
68
Step-by-step explanation:
because 180-44=136
136:2=68 (since TRS=TSR, there is formula)
Answer liner
Step-by-step explanation:
Answer:
angle 3 is 140°
Step-by-step explanation:
angle 2 and angle 3 are equal
angle 4 and 1 are also equal
angle 3 =
180-40= 140
angle 3 is 140
