Answer:
Correct answer is x = 28°
Step-by-step explanation:
Okay we know Angle A is 2x + 2
Angle B is 90
Angle C is 180 - 148 = 32 ( straight line angle is 180)
Sum of all angles should be 180 in a triangle
which means
A + B + C = 180
2x + 2 + 32 +90 = 180
2x + 124 = 180
2x = 180-124
2x = 56
x = 56/2
x = 28
D.
y= 4x+3
When multiply the X’s with four and then adding three gets the Y’s.
For example 4•10=40+3 equals 43 therefore it’s ( 10, 43 )
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
