One side of triangle is 7 more than 2 times the shortest side. the third side is 15 centimeters more than the shortest side. the
nikdorinn [45]
X = longest side , y = middle side , z = shortest side 

P = x + y + z
P = 82
x = 2z + 7
y = z + 15

82 = (2z + 7) + (z + 15) + z...combine like terms
82 = 4z + 22
82 - 22 = 4z
60 = 4z
60/4 = z
15 = z

so the shortest side (z) is 15 cm
the second side (y) is : z + 15......15 + 15 = 30 cm
and the longest side (x) is : 2z + 7.....2(15) + 7 = 37 cm

Find the missing value in each figure below. What does “y” equal?
finlep [7]

Answer:

Step-by-step explanation:

The perpendicular is equal to 6. That's because the left triangle's missing angle is 180 - 45 -90 = 45

The angle in the right triangle is given as 52.

The cos(52) = adjacent side (which we just found to be 6) / y

Multiply both sides by y

y cos(52) = 6

cos(52) = 0.6157

Divide by sides by cos(52)

y = 6 / cos(52)

y = 6 / 0.6157

y = 9.76

tan13pi/4 A. Use the fact that there are 2pi radians in each circle to find another angle, smaller than 2 pi, that is equivalent
DanielleElmas [232]
Hello : 
13π/4  = (16-3)π/4
            = 16π/4 -3π/4
  13π/4  = -3π/4 +4π   
 tan( 13π/4) = tan ( -3π/4)= -  tan ( 3π/4)  =- tan( π - π/4) = - tan(- π/4)
tan( 13π/4) = -(-tan(π/4)) =tan(π/4)=1
