Good job, heureka!!!
2) B. 2 X 15 = 30 P = 34
x + 30 = 3x - 10
x = 20
Here's the answer according to your textbook:
240 / 26 = 9.230769231
Angle DAN = arctan( 10/20 ) = 26.565º
AP = PS = PQ = cos (26.565º) * 10 = 8.94427191
The area of a square PQRS = PS * PQ = 80 cm2
The length of AC = sqrt( 62 + 22 ) = 6.32455532
The length of BC = AC / 4 = 1.58113883
The coordinates of point B => B (3.5, 0.5)
The lengths of the sides of a triangle are 10, 17, and 21. How long is the altitude of the triangle to the longest side?
a = 10 b = 17 c = 21
1/ Find semiperimeter ( s )
2/ Find the area of a triangle ( A )
3/ Find the height => hc = 2A / c
The measure of the altitude drawn from the vertex of the right angle of a right triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.
Knowing that x = sqrt( 10 * 6 ) = 7.745966692
It didn't work; it was wrong!!!!
In XYZ, and X = 90° , and cos Z = 7/ 25. Find sin Z and tan Y.
cos(Z) = 0.28
sin(Z) = 0.96
tan(Y) = 0.2916666666666666
