Answer:
Step-by-step explanation:
we know that If two angles are complementary, then their sum is equal to 90 degrees
Letx -----> the measure of an angle
y-----> the measure of he other angle
we know thatx+y=90 -----> y=90
-x -----> equation
Ax=y+54 ----> equation
Bsubstitute equation B in equation A and solve for yy=90-(y+54)
y=90-y-542y=36y=18°
Find the value of xx=y+54 -----> x=18+54=72°
thereforeThe measure of the angles are 72 degrees and 18 degrees
Answer:
5
Step-by-step explanation:
60÷6 is 10
54÷6 is 9
30÷6 is 5
The correct answer is: [B]: " 0.703 < 0.73 " .
_______________________________________________
34 + 0 + 18 + 26
= (34 + 26) + (0 + 18)
= 60 + 18
= 78
Used:
a + b = b + a - commutative property
0 + a = a - identity property
