Answer:

a) The value of x is 15.89 (don't know if I have to round, sorry)

b) The last angle in the triangle is 39 degrees

Explanation:

Here, we see that x is the hypotenuse,

Using SOHCAHTOA,

if we have the 51 degree angle,

then the adjacent is 10 and we can use CAH to find the hypotenuse = x

cos(51) = adjacent/hypotenuse = 10/x

x = 10/cos(51)

x = 15.89

b) since the sum of the angles in any triangle is 180 , we have,

y + 51 + 90 = 180,

y = 180 - 90 - 51

y = 39 degrees
