Answer:
The third one
Step-by-step explanation:
Since the angles are a linear pair, then we have to validate the following equation:
m∠1 + m∠2 = 180
Substituting the values we have:
(x - 29) + (x + 61) = 180
We clear x:
2x + 32 = 180
x = (180-32) / (2)
x = 74
Therefore, each angle will be:
m∠1 = x - 29 = 74 - 29 = 45
m∠2 = x + 61 = 74 + 61 = 135
Answer:
the measure of each angle are:
m∠1 = 45
m∠2 = 135

Find the number of square yards
Area = L * w
L = 2
w = 1
Area = 2 * 1
Area = 2
Now for the counter top
1 sq yard costs 204.63
2 sq yards cost 2 * 204.63
2 sq yards cost 409.26
Answer: 409.26
Answer:1/4
Step-by-step explanation:
1/2 is the same thing as 2/4 so.... 2/4 minus 1/4 is 1/4
Answer:sin F = 4/5
cos F = 3/5
tan D = 3/4
Explanation:First, we have sin an angle = 4/5
In a right-angled triangle:
sin theta = opposite / hypotenuse
This means that in triangle DFE:
The hypotenuse = 5 units
one of the sides = 4 units
Use Pythagorean theorem to get the other side as follows:
hypotenuse^2 = side1^2 + side2^
25^2 = 4^2 + side2^2
side2^2 = 9
The second side of the triangle = 3 units
The special trig functions are as follows:
sin theta = opposite / hypotenuse
cos theta = adjacent / hypotenuse
tan theta = opposite / adjacent
From the attached figure and based on the calculations above:
sin F = 4/5
cos F = 3/5
tan D = 3/4
Hope this helps :)
