Answer:
x = 40 and y = 70
Step-by-step explanation:
This is an isosceles triangle since the two sides adjacent to the x angle are the same length. The angle opposite the 110 is 70 since these are supplementary angles. Angle y is 70 (isosceles triangle has two sides equal and two angles equal). The sum of the interior angles of a triangle is 180, so x = 180 - 70 - 70 = 40.
Answer:
Step-by-step explanation:
It's the right triangle. The formula of an area of a right triangle:
We have:
Use tangent:
Substitute:
<em>convert the decimal to the fraction</em>
<em>cross multiply</em>
<em>divide both sides by 14281</em>
Calculate the area:
Answer: 6.
We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number.
The interior angel of 7 will be angel 4
∠7 + ∠4 = 180°
