Answer:
A = 24.96 yd^2
Step-by-step explanation:
We need to find the area of the room
Area is length times width
A = lw
We know the length is 5.2 yds and the width is 4.8
A = 5.2 * 4.8
A = 24.96 yd^2
Answer:
Step-by-step explanation:
product of (2.5 x 10²) x (10⁵)=2.5 x 10⁷
when we multiply the powers we add the 2+5=7
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
