Answer:
Perimeter of the triangle is units
Step-by-step explanation:
Given a degree angled triangle
Let us calculate the length of side opposite the 30 degree angle
hypotenuse
units
length of side opposite the 60 degree angle
units
The perimeter of a triangle is equal to the sum of length of all three sides
Thus, the perimeter of this degree angled triangle is
units
Thus, the perimeter of the triangle is units
Answer:
The surface area of the can is
Step-by-step explanation:
we know that
The surface area of a cylinder (can of soup) is equal to
we have
----> the radius is half the diameter
substitute the values
Here, as the tangents are given above in variable length with radius of the circle as r = 4.4 cm, we get as
since the sides opposite to the equal angles are always equal we get as,
x-2 = 2x-10
===> -2 +10 = 2x-x
==> 8 = x
hence the measurement of the Tangents is,
putting x = 8
2(8)-10 ==> 16-10 ==> 6 cm
length of each tangent is 6 cm.
The answer is -2x+4 hope that helps your welcome have a good day
x + y = 16, and x - y = 12. Get x by itself. Subtract y from both sides in the 1st equation to get x = 16 - y. Add y to both sides in the 2nd equation to get x = 12 + y. Put the parts together. 16-y=12+y. Add y to both sides to get 16 = 12 + 2y. Subtract 12 to get 4 = 2y. Divide both sides by 2 to get y = 2. Replace it with the 1st equation to get X + 2 = 16. Subtract 2 from both sides to get X = 14.
