Answer:
61°
Step-by-step explanation:
let the angle on a straight line with 112° be x
112°+x = 180° ( angles on a straight line)
x = 180°- 112°
x = 68°
calculating for k°
68°+ k +51° = 180° (sum of angles Ina triangle equal 180°)
119° +k = 180°
K = 180-119
k = 61°
The slant height is the hypotenuse of a right triangle with sides length 7 m and 19 m. Use the Pythagorean theorem.
h² = (7)² + (19)²
h² = 49 + 361
h² = 410
h = √(410)
h = 20.25
rounded to nearest whole number would be 20 m
Answer:
36.61
Step-by-step explanation:
In the given figure, if the lines p and q are parallel then the angles 4 and 1 form the pair of co - interior Angles that sum upto 180°,
so,
