Answer:
C. 80°
Step-by-step explanation:
I believe it's 80 l
: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
In this problem
Triangles EFG and YXZ are similar by AA Similarity Theorem
Because
m∠F ≅ m∠X and m∠E ≅ m∠Y
Remember that in a triangle the sum of the interior angles must be equal to 180 degrees
so
m∠G ≅ m∠Z
we have
m∠E = 62°
m∠X = 80°
Remember that
m∠F ≅ m∠X
therefore
m\angle F = 80^om∠F=80o
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
we have here 2 triangles : the larger, outer shaded one, and the smaller, inner white one.
to get the area of the shaded part, we need to calculate the area of the large triangle and subtract the area of the smaller triangle.
large area :
12 × 15 / 2 = 6 × 15 = 90 ft²
small area :
8 × 10 / 2 = 4 × 10 = 40 ft²
the shaded area is
90 - 40 = 50 ft²
Answer:
The Definition of Inverse Operations
A pair of inverse operations is defined as two operations that will be performed on a number or. variable, that always results in the original number or variable. Another way to think of this is. that the two inverse operations “undo” each other.
Example: Addition and subtraction are inverse operations.
To find a number 10 times smaller than 62 simply move the decimal point one place to the left.
The decimal point in 62 is at the end of the number. 62. becomes 6.2 if we move the decimal one place back.
