Answer:
3
Step-by-step explanation:
To ease your live re write each one by using sin, cos, tan, knowing well that:
cscx = 1/sin x ( sin of an angle = opposite side/hypotenuse(23)
secx = 1/cos x (cos of an angle = adjacent side/hypotenuse(23)
cotx = 1/tanx (tan of an angle = opposite side/adjacent side)
Work it out & if you have difficulties do let me know
Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120
