Find the value of the letter in each of the following. Give your answers to 1 d. p.

Step-by-step explanation:

z=45

in right triangle

One angle is always 90°

z+z+90=180

2z=90

z=45

2)similarily of the first one but doing same on both side

45+45=90

s=90

3) cos 45=adj/hyp

cos45=x/2

(cos45=1/√2)

1/√2=x/2

2/√2=x

2x√2/√2x√2=x

2√2/2=x

x=√2 cm

step-by-step explanation:
