(1,-2) because their is no line on the -2
Answer:
15
Step-by-step explanation:
Let the left side of the triangle be 2Y for the bigger triangle and then the smaller one will be Y.
Comparing the two triangle
2Y/Y = 30/X
2 = 30/X
Cross multiple
2X = 30
Dividing by 2
X = 30/2
X = 15
Answer:
x has a value of 71, making D the correct answer.
Step-by-step explanation:
Because this is an isosceles triangle, we know that the bottom two angles are equal. We also know that the sum of the angles inside a triangle will always come to 180°. With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.

So the correct answer is D, 71 degrees.
Answer:
(a) The product of the sum of a and b and their difference.

(b) The tripled product of 6a and b².

(c) The difference of the squares of 2m and 7n.

26.34 I believe is the correct answer
