Answer:
46.3cm
Step-by-step explanation:
- perimeter is length around shape
- 25/2 multiply by 2 becoz it's got two equal sides
- 32/3 multiply by two for the other equal sides
- add answers together to give you
- 46.3cm
Ah yes, good ol’ Pythagorean’s theorem.
The hypotenuse is the opposite of the 90 degree angle, the longest side of the triangle.
The legs are opposite of the acute angles
Formula: a^2 + b^2 = c^2
2:
Let’s plug in some values
(6)^2 + (3)^2 = c^2
C = 6.7
The side will be 6.7 units
3)
Let’s plug in some values
(13.3)^2 = (9.7)^2 + (b)^2
(13.3)^2 - (9.7)^2 = b^2
176.89 - 94.09 = b^2
b = 9.1
The side will be 9.1 units
-6 < x (less than or equal to) 8
Answer:
y = -3x +5
Step-by-step explanation:
parallel lines so slope of the lines will be equal.
m1 = m2
y = mx + b,
y = -3x + b
substituting y = -1 and x = 2
-1 = -3(2) + b
-1 = -6 + b
therefore, b = -1 + 6
b = 5
by substituting b = +5
therefore, the equation is,
y = -3x + 5
