Step-by-step explanation:
Answer:
x = 75°
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
Therefore,
78° + 27° + x° = 180°
Add like terms
105 + x = 180
105 + x - 105 = 180 - 105 (substraction property of equality)
x = 75°
Answer:
cos 30° =767.6/hypotenus
(make h the subject of the formular)
h = 767.6/cos 30°
h =767.6/0.154
h =4,985
approximately 5,000
Answer:
1 and 6/35
Step-by-step explanation:
You would want to multiply the denominators with the same number.
5×7
Multiply the numerators as well.
3×7 and 4×5
The fractions you would have now is 21/35 and 20/35, you can now add them up without having difficulties if the denominator is the same number.
You can also change it into decimals but I suggest this strategy.
Yes, because the x doesn’t repeat. The y is not as important so it’s fine if it repeats numbers.
