For this you will need to calculate the number of sweaters - 7x. Then you need to calculate the number of shirts - 9y. Last you need to calculate the number of pants - 12z. To balance the equation, you must calculate the total price $172+$269+$74 = $515. The equation is 7x+9y+12z = $515.
Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.
Area of the Semi Circle:
Formula: A = (πr²)/2
The radius is the diameter divided by two (16 / 2 = 8)
A = (π*8²)/2
A = (π64)/2
A = 200.96/2
A = 100.48 meters
The area of the semi circle is 100.48 meters
Area of the Triangle:
Formula: A = bh/2
A = 16*12/2
A = 192/2
A = 96 meters
The area of the triangle is 96 meters.
To find the total area of the shape, we can add.
100.48 + 96 = 196.48 meters.
Best of Luck!
-15a - 9c -6 should be right :)
Answer:
2x + 120 = 180 (being co interior angle)
or, 2x = 180 - 120
or, 2x = 60
or, x = 60/2
or, x = 30
therefore 2x = 2* x = 2* 30= 60
Answer:
AC congruent to EC
Step-by-step explanation:
This problem is asking specifically to prove triangles congruent using HL.
HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.
Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.
You need AC congruent to EC.
