Answer:
the third obtuse angle is 110°.
Step-by-step explanation:
From the question, the 0s at the back of the given angles are meant to be degrees (°), since the sum of angles in a triangle cannot exceed 180°.
Hence, The question would be:
The two angles of an obtuse triangle are 23° and 47°. Find the third obtuse angle
.
Step-by-step explanation:
In a triangle, there are three (3) angles which sum up to 180°.
Two of the angles are given which are 23° and 47°. Now, to determine the third angle which is an obtuse angle.
(NOTE: An obtuse angle is a type of angle that is greater than 90° but less than 180°).
Let the third obtuse angle be x
Then , we can write that
23° + 47° + x = 180° (Sum of angles in a triangle)
Then,
70° + x = 180°
x = 180° - 70°
x = 110°
Hence, the third obtuse angle is 110°.
Answer:
10/81
Step-by-step explanation:
let,
y=kx
y=10 when x=9
so,
10=k×9
or, k=10/9
when x=1/9
y=kx
or, y=(10/9)×(1/9)
or, y=10/81
Set each equation equal to zero.
y + 5 = 0
Subtract 5 from both sides.
y = 0 - 5
y = - 5
y - 9 = 0
Add 9 to both sides
y = 0 + 9
y = 9
y = - 5, 9
Answer:
y =20
Step-by-step explanation:
5(y+4)=6y
Distribute
5y +20 = 6y
Subtract 5y from each side
5y-5y+20=6y-5y
20 =y
<h2>527.52</h2>
Step-by-step explanation:
radius (r) = 6
height (h) = 8
total surface area = 2π×r×h + 2πr²
= (2×3.14×6×8) + (2×3.14×6×6)
= (301 44) + (226.08)
= 527.52
