Answer:
x = 61
Step-by-step explanation:
Left hand triangle containing 1 angle of 74
Label the other angle opposite the marked side also as 74
Find the third angle. Call it y.
y + 74 + 74 = 180 Combine like terms
y + 148 = 180 Subtract 148 from both sides.
y = 180 - 148
y = 32
=============
Now work with the triangle on the right.
label the angle making up the right angle = z
32 + z = 90 These two angles are complementary = 90
32 - 32 + z = 90 - 32 Subtract 32 from both sides
z = 58 Use 58 wherever you see z
x + x + z = 180 Substitute
2x + 58 = 180 Subtract 58 from both sides
2x = 122 Divide by 2
x = 61
Answer:
A. t(x) = 450 - 0.06x
Step-by-step explanation:
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
So,
450 - 0.06x
Answer:
61 degrees
Step-by-step explanation:
A right angle equals 90 degrees.
90-29= 61
Hey there!
12 ≥ 5f - 18
5f - 18 ≤ 12
ADD 18 to BOTH SIDES
5f - 18 + 18 ≤ 12 + 18
SIMPLIFY IT!
5f ≤ 30
DIVIDE 5 to BOTH SIDES
5f/5 ≤ 30/5
SIMPLIFY IT!
f ≤ 6
Therefore, your answer is: f ≤ 6
Good luck on your assignment & enjoy your day!
