Answer:
105
Step-by-step explanation:
The sum of four exterior angle is always 360 degrees for a quadrilateral
95+ 70+90+b = 360
Combine like terms
255 +b = 360
Subtract 255 from each side
255+b-255 = 360-255
b = 105
Answer:
18
Step-by-step explanation:
Assuming the sides are 12 and 38
Since this is a right triangle, we can use trig functions
We know the opp side and the adj side of the angle in questions
tan ? = opp /adj
tan ? = 12/38
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/38)
?=17.52556
To the nearest degree
? = 18
If the side is 36,
tan ? = opp /adj
tan ? = 12/36
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/36)
?=18.43494
To the nearest degree
? = 18
17 goats in the barn and 8 go outside.
9 goats are still in the barn
because seventeen minus eight = nine
