Answer:
x = 3
Step-by-step explanation:
Given
4 : 8 = x : 6, expressing in ratio form, that is
= ( cross- multiply )
8x = 24 ( divide both sides by 8 )
x = 3
Thus 4 : 8 = 3 : 6
The area of the resulting figure will be given by:
∫f(x)dx
f(x)=13/2x^3
thus
∫f(x)dx=13/2∫x³dx=13/8[x^4]
integrating over the inerval
13/8(12^4)-13/8(5^4)
=32680+3/8 sq. units
=
If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~
- Obtuse = one side is more than 90 degrees
- Acute = all sides are less than 90 degrees
- Isosceles = two sides are of the same length
- Equilateral triangle: all angles are of same measure (60)
- Scalene: all sides are of different lengths
- Right Triangle: One of the angles equals 90 degrees.
