Answer:
A
Step-by-step explanation:
The two angles in the triangle in the question are 58 degrees and 54 degrees.
Three angles in a triangle add up to 180 degrees
58 + 54 + x = 180
112 + x = 180
subtract 112 on both sides
x = 180 - 112 = 68 degrees
Only option A has a triangle that has the same angles, thus triangles are similar.

Answer:
72.7 is the weighted average score
Step-by-step explanation:
The weighted average score
= score of lab * % share of total grade + score of first major test * % share of total grade + score of second major test * % share of total grade + Score of the final exam * % share of total grade
Substituting the given values, we get -
0.23 * 74 + 0.25 * 69 + 0.25 * 62 + 0.27 * 85
= 72.7
Answer:
Step-by-step explanation:
bx-c=ax+d
<=> bx-ax=c+d
<=> (b-a)x=c+d
<=> x=(c+d)/(b-a)
Answer:
Step-by-step explanation:
radius of a coin is 12 mm
Diameter of the coin is twice the radius = 2 x 12mm = 24mm
The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m
Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²
what is the area of the coin
