i believe this is the answer :)
To find the diameter of the circle it’s C=(2)(3.14)(r) radius is 8/2 which is 4 so 2(3.14)(4) is 25.13 + 36 is 61.13
The perimeter of the whole figure is 61.13in^2
Answer:
-563
Step-by-step explanation:
a = -7 , b = 9 , c = 4
9ab +C
9 × -7 × 9 + 4
81 × -7 + 4
-567 + 4
-563
Answer:
m∠KJL = 54°
Step-by-step explanation:
In ΔJKL,
m∠JKL = 72°
JK ≅ KL
Since, two sides of ΔJKL are congruent, triangle is an isosceles triangle.
By the property of an isosceles triangle,
Opposite angles of the congruent sides of an isosceles triangle are equal in measure.
Therefore, ∠J ≅ ∠L
By the property of a triangle,
Sum of all interior angles of a triangle is 180°.
m∠J + m∠K + m∠L = 180°
m∠J + 72° + m∠J = 180° [Since, m∠J = m∠L]
2m∠J = 180° - 72°
m∠J = 54°
Therefore, m∠KJL or m∠J is 54°.
