Answer:
f=8
Step-by-step explanation:
0.62(f+(-6)+6.96=8.2
0.62(f-6)+6.96=8.2
multiply both sides by 100
0.62(f-6)*100+6.96*100=8.2*100
Refine
62(f-6)+696=820
Subtract 696 from both sides
62(f-6)+696-696=820-696
Simplify
62(f-6)=124
Divide both sides by 62
62(f-6)/62 = 124/62
Simplify
f-6=2
add 6 to both sides
f-6+6=2+6
simplify
f=8
Answer:
(-1, -3)
Step-by-step explanation:
The given equations are:

and

Equating (1) and (2):

The two values of x are repeating in nature i.e. x = -1
So, value of
is -1.
Putting value of
in equation (1):

The solution is represented as (
)
So, the solutions are :
<em>(-1, -3)</em>
Answer:
m∠FAD=48°
Step-by-step explanation:
we know that
The<u><em> Perpendicular Bisector Theorem</em></u> states that: A radius that bisect a chord is perpendicular to the chord
we have
FD=DE
The radius AC bisect the chord FE
so
AC is perpendicular to FE
The triangle FAD is a right triangle
m∠FAD+m∠AFD=90° ---> by complementary angles in a right triangle
we have
m∠AFD=42°
substitute
m∠FAD+42°=90°
m∠FAD=90°-42°
m∠FAD=48°
Answer:
52
Step-by-step explanation:
Step 1:
AB + BC = AC
Step 2:
26 + BC = 78
Step 3:
BC = 78 - 26
Answer:
BC = 52
