Answer:
480 inches squared
Step-by-step explanation:
The formula for the area of a rhombus is pq/2, where p and q are the diagonals. In the picture, half of a diagonal is 10 (which I am assuming 10 does not represent the whole diagonal), so all of the horizontal diagonal is 20.
Applying the Pythagorean Theorem to this, we get 10^2 + x^2 = 26^2. After simplifying, this becomes 100 + x^2 = 676, and therefore x = 24. Multiply this by 2 to get the full vertical diagonal, the area is simply 48*20/2 which is 480 inches squared.
Answer:
y = 107°
Step-by-step explanation:
As you can see from the markings on the triangle, this is an isosceles triangle (two sides are congruent).
An isosceles triangle has the base angles congruent too.
So at this point,
34 = x - 5
Solve for x,
34 = x - 5
x = 34 + 5
x = 39
Now, the total angle measure of triangle is 180°.
There are two angles ready to solve for y.
34 + 39 + y = 180
73 + y = 180
y = 180 - 73
y = 107°
