If x and (x+50°) are complementary angles. find the angles
2 answers:
Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.
So
x + x + 50° = 90°
2x = 90° - 50°
2x = 40°
x = 40°/2
x = 20°
x + 50 = 20 + 50 = 70°
Hope it helps :)
Answer:
let 1 s t angle be x
and another angle be x + 5 0 °
<em>two angles are said to be</em> <em> </em> <em>complement</em> <em>ary</em> <em>,</em> <em>if</em> <em> </em> <em>the</em> <em> </em> <em>some</em> <em> </em> <em>of</em> <em> </em> <em>their</em> <em> </em> <em>measures</em> <em> </em> <em>is</em> <em> </em> <em>9</em> <em>0</em> <em>°</em>
so ,
x + x + 5 0 = 9 0
2 x + 5 0 = 9 0
2 x = 9 0 - 5 0
x = 4 0 / 2
: -x = 2 0 . . . . . . . 1 s t angle
an other angle ( x + 5 0 ) = 2 0 + 5 0 = 7 0 °

Percent error = |actual error - expected error/ expected error| * 100%
(|75-95|)/95 = 0.21
0.21 * 100% = 21% error
