Answer:
If the first number is x and y is the second number
x = 11
y = 18
Step-by-step explanation:
If x is the first number and y is the second number then:
x + 7 = y
The sum of the two numbers is expressed as:
x + y = 29
In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation
x + y = 29
x + (x + 7) = 29
2x + 7 = 29
2x + 7 - 7 = 29 - 7
2x/2 = 22/2
That means x equals 11
Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y
11 + 7 = y
y = 18
By the ASA postulate we figure that:
Angles C and D are equal (noted by the line through these angles)
Lines CB and DE are parallel and equal in length (noted by the double line through these sides)
Angle B and E are both 90° (noted by the square at each of these angles)
From this information, we can say that triangle CBA = triangle DEA is true.
