Area of a triangle is given by half the product of two of the sides and the sine of the included angle.
Thus, the area of the triangle is 0.5 x 27.6 x 30 x sin 23^o = 161.76 cm^2
X - y = 8
x + 2 = 3y.....x = 3y - 2
3y - 2 - y = 8
2y = 10
y = 5
x - y = 8
x - 5 = 8
x = 8 + 5
x = 13
so x = 13 and y = 5
Answer:
x=17.771mm
Step-by-step explanation:
given a right triangle
to find vslue of x
solution (perpendicular) ² + (base) ² =(hypotenus) ²
using pythagorus theorem
(16.5)²+(6.6)²=(x)²
272.25+43.56=(x)²
315.81=(x)²
√315.81=x
x=17.771mm
Okay so you take the tan43=x/12
tan43(12)=x
11.2=x
