Answer:
in triangle MNO
relationship between perpendicular and hypotenuse is given by sin angle
sin64°=p/h=70/x
x=70/sin64°=77.88foot
length of MN to the nearest tenth of a foot.
=78ft
Answer:
Step-by-step explanation:
<u>We know that the perimeter is the sum of side lengths.</u>
<u>Substitute the values and solve for x:</u>
- x + 2x - 2 + 3x + 1.5 = 11.5
- 6x - 0.5 = 11.5
- 6x = 12
- x = 12/6
- x = 2
Sum of all the angles in a triangle = 180 degrees.
it's given is an acute angle so <90
degrees now one is 38 the sum of other two would be 142 now here 27 is not possible because then the third angle, would be 115 degrees.
hope this help
Answer:
acute, isosceles
Step-by-step explanation:
Acute: all angles are less than 90°
Isosceles: 2 sides are the same length, the other is not
Have a great day! :D
