Answer:

10.5 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (a + b)

where h is the height and a, b the parallel bases

Here h = OS = 3, a = OC = 5 and b = SK = 2, thus

A = 0.5 × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Answer:

Step-by-step explanation:

a = 2 units

b = 5 units

height (h) = 3 units

Area=\frac{(a+b)*h}{2}\\\\=\frac{(2+5)*3}{2}\\\\=\frac{7*3}{2}=\frac{21}{2}\\\\=10.5square units

Can someone help me with this last one
Lena [83]
The answer is C because the triangles are congruent by angle side angle theorem. Two sets of matching angles with a pair of matching sides in between.
when solving questions like these always skip the whole flip it over part. look at the measurements and the order they are in across the shape and find the pattern in the answer.

Bracelet cost = b
Necklace cost = n

15b + 8n = 500
19b + 24n = 980

Elimination method x -3
-45b - 24n = -1500
19b + 24n = 980

-26b = -520
b = $20 bracelets

Plug back in
19(20) + 24n = 980
380 + 24n = 980
24n = 600
n = $25 necklaces


Check:
15(20)+ 8(25)= 500
300 + 200 = 500
500 = 500 :)
