Perimeter of the shape is 2(AB) + 2(BC)
AB = sqrt((7 - 5)^2 + (3 - 5)^2) = sqrt(2^2 + (-2)^2) = sqrt(4 + 4) = sqrt(8) = 2.83
BC = sqrt((3 - 7)^2 + (0 - 3)^2) = sqrt((-4)^2 + (-3)^2) = sqrt(16 + 9) = sqrt(25) = 5
Perimeter = 2(AB) + 2(BC) = 2(2.83) + 2(5) = 5.66 + 10 = 15.7
Answer:
x = 110
Step-by-step explanation:
all angles of the triangle MUST add up to 180 degrees.
45 + 65 = 110
180 - 110 = 70
since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too
180 - 70 = 110
n - the larger of two i ntegers
m - the smaller of two integers
n + m = 74 → n = 74 - m
n = 2m + 26
Therefore we have:
2m + 26 = 74 - m |subtract 26 from both sides
2m = 48 - m |add m to both sides
3m = 48 |divide both sides by 3
m = 16
n = 74 - 16 = 58
Answer: 16 and 58.
Answer:
a = 45°
Step-by-step explanation:
In triangle PSR
PS = RS (Given)
angle SPR = angle SRP (isosceles triangle property)
Let angles SPR and SRP be x
Therefore, 90° + x + x = 180° (angle property)
=> 90° + 2x = 180°
=> 2x = 180° - 90° = 90°
=> 2x = 90°
=> x = 90° ÷ 2 = 45°
=> x = 45°
Hope it helps:)
