20 degrees, because 70 degrees+ 90 degrees (what’s given) = 160 degrees. And then the entire sum of a triangle all the degrees always = 180, so 180-160= 20!

Answer:

20 degrees

Step-by-step explanation:

One angle is 70 degrees and the other is 90. Angles of a triangle add up to 180. 180 - 70 - 90 = 20. The final angle is 20 degrees.

Hey! 
First, you would take 349 and subtract 25 from it.(349-25=324) This gets rid of the down payment. 
Next, you would divide 324 by 54. (324÷54=6)
It would take him 6 weeks! 
Hope this helped! And make sure to check my calculations! 
Godspeed

A gutter at the edge of a roof drops 2 inches for every 30 feet of length. The measure of the angle to the nearest tenth of a de
g100num [7]
About 0.3 degrees, by estimation.  
The sixty-to-one rule is useful here.  At a distance of 60 units, the angle in degrees and the distance (in units) are about equal for small angles.  
Thirty to two inches is the same as sixty to four inches, about a third of a foot, so the angle must be about a third of a degree.  Rounded it gives 0.3.

In quadrilateral QRST, angle rst measures (5x + 15)o. Angle TQR measures (4x + 3)o.
sattari [20]
2(5x + 15) + 2<span>(4x + 3) = 360
10x + 30 + 8x + 6 = 360
18x = 324
    x = 18

so

RST = </span><span>5x + 15 = 5(18) + 15 = 105

answer

RST = 105 degree</span>
