sorry if it don't make sense ;c
Answer:
relationship between base and hypotenuse is given by cos angle
let angle be ø
cos ø=b/h
cosø=28/34
ø=cos-¹(28/34)=34.5°
Answer:
x = 7 and 3/2
Step-by-step explanation:
We can say:
x - 7 = 0 and 2x - 3 = 0
<em>Lets solve for x - 7 = 0 first:</em>
Add 7 to each side of "="
=> <u>x = 7</u>
<em>Now lets solve for 2x - 3 = 0</em>
First add 3 to each side of "="
=> 2x = 3
Now divide each side by 2
<u>=> x = 3/2</u>
Hope this helps!
