Answer:
one
Step-by-step explanation:
2 + x = 6
x=6-2
x=4
Answer and Step-by-step explanation:
The mistake is that the sign (<) isn't flipped.
When a negative number is multiplied, the sign of the inequality flips to go the other way, so < would go >.
Answer:
a. Angle Y is a right angle.
b. The measure of angle Z is 45°.
e. The perpendicular bisector of creates two smaller isosceles triangles.
Step-by-step explanation:
Let x represent the measures of base angles X and Z. Then 2x is the measure of vertex angle Y, and the sum of angles is ...
x + x + 2x = 180°
x = 45°
2x = m∠Y = 90°
so the triangle is an isosceles right triangle which has base angles of 45°.
The perpendicular bisector of XZ is the altitude of the triangle XYZ. It creates two smaller right triangles with acute angles of 45°. Hence, those, too, are isosceles right triangles.
