Answer:
1465.1 cm²
Step-by-step explanation:
El espejo en forma de diamante tiene la forma de rombo
Tenga en cuenta que: las diagonales del rombo tienen las mismas medidas de esos lados
Por lo tanto, el área del espejo se calcula como:
1/2 × Diagonal 1 × Diagonal 2
Diagonal 1 = 80.5 cm
Diagonal 2 = 36.4 cm
= 1/2 × 80.5 cm × 36.4 cm
= 2930.2 cm² / 2
= 1465.1 cm²
Por tanto, el área del espejo es 1465.1 cm².
<span>i can.
it says you got 8 pens.
1.09h + .69(8) = 7.52
1.09h + 5.52 = 7.52
do you know what to do from here?</span>
In a triangle all of the angles always add up to 180, so let's set up an equation.
79 + 37 + y = 180
Simplify
116 + y = 180
Subtract 116 from both sides.
y = 64
The value of y is 64.

If shapes are congruent, then they are mathematically equal (same dimensions, angles etc.). So just locate where the angle x is on both triangles, it should have a value on or a calculable value on the other. If you provide us with the actual sheet I could walk you through it.
