Answer:
The measure of side AC is 6 cm.
Step-by-step explanation:
The information for the triangle ABC are:
AB = 6 cm
m∠A = 80°
m∠B = 50°
The sum of all angles of a triangle is 180°.
Compute the value of m∠C as follows:
m∠A + m∠B + m∠C = 180°
m∠C = 180° - 80° - 50°
= 50°
Thus, the angles, m∠C = m∠B.
Consider the triangle below.
If two angles of a triangle are equal or similar then that triangle is known as an isosceles triangle.
And in an isosceles triangle the sides corresponding to the equal angles are equal.
Then in this case as m∠C = m∠B then sides AC = AB.
The measure of the side AC is 6 cm.
The circle is being dilated by a factor of 8 so the radius will be 8 times the original radius (4 ft).
The circumference of a circle =
, so if r is replaced by
we get
or just
.
Basically the circumference will be 8 times the original circumference.
If you plug in the original radius, into this new formula you get
The area of a circle =
, so if r is replaced by
we get
or just
Basically the area will be 64 times the original area.
If you plug in the original radius into this new formula you get
The answers are A, C, F, G, and H
Answer:
Eleana is 20 years old
Her grandfather is 80 years old
Step-by-step explanation:
Eleana = E
Grandfather = 4E
4E + E = 100
Add
5E = 100
Divide
E = 20
Eleana is 20 years old
Her grandfather is 80 years old
