Answer:
you do what it says so 13=x
Step-by-step explanation:
Answer:
(-60/11,111/11)
Step-by-step explanation:
Solving simultaneously, 4x - 3y=6
-3(6x + y=42)
then it becomes, 4x - 3y=6
-18x - 3y= 126 subtracting the two equations,
22x= -120, x= -60/11 and y = 111/11
Answer:
-0.9
Step-by-step explanation:
(-3.4+4.3)+a=0
0.9+a=0
a=0-0.9
a=-0.9
Angle B = ADC arc / 2
32 = ADC arc / 2
ADC arc = 2 × 32
ADC arc = 64
_________________________________
ADC arc + ABC arc = 360
64 + ABC arc = 360
ABC arc = 360 - 60 - 4
ABC arc = 300 - 4
ABC arc = 296
_________________________________
Angle D = ABC arc / 2
x = 296 / 2
x = 148
_________________________________
Angle A = x - 40
Angle A = 148 - 40
Angle A = 108 degrees
Answer: 48 sq. cm
Step-by-step explanation:
The area of the similar shapes is similar.
We use scalar factor to get the area of the bigger or the smaller figure by using the area of the given figure.
In the given figure , Area of the small pentagon = 32 sq. cm
Scale factor for the bigger pentagon = 1.5
Then , the area of the bigger pentagon would be = (Scale factor) x (Area of the small pentagon)
= 1.5 x (32 sq. cm)
= 48 sq. cm
Hence, the area of the larger pentagon = 48 sq. cm
