Solve the equation for principal values of x. Express solutions in degrees.
sqrt2 sinx - 1 = 0
a. 90
C. 315
b. 45°
d. 270

i think is B=45

Step-by-step explanation

answer:

c. the third graph

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
