Question

Find the value of x in the triangle. 45-45-90. PLASE HELP!!!

Answer 1

2) X = 14 and y = 19.8

3) X = 25.45

5) X = 5.66

6) X = 7.07

Explanation:

2) tan45° = 14/x

x(tan45) = 14

x = 14 / tan45

x = 14

`y = \sqrt{14 ^(2) + 14 ^(2) }`

y = 19.79

3) cos45 = 18/x

x(cos45) = 18

x = 18/cos45

x = 22.45

5) cos45 = x/8

8(cos45) = x

x = 5.66

6) cos45 = x/10

10(cos45) = x

x = 7.07
