61°
Step-by-step explanation:
In ΔQRS,
Let ∠Q = ∠S = x
Therefore, we know
Sum of all angles in a triangle = 180°
So,
∠QRS + ∠QSR + ∠RQS = 180°
58° + x + x = 180°
58° + 2x = 180°
2x = 180 - 58°
x = 122°/2
x = 61°
Therefore,
∠Q = ∠ S = 61°

Answer:
the correct answer would be -2f+7
Answer:
X = 53 degrees
Y = 74 degrees
Z = 53 degrees
Step-by-step explanation:
So if you knew that all angles in triangles add up to 180 degrees. You first want to find Y. 180 - 36 - 70 is equal to 74. So, Angle Y is 74 degrees. Line XYZ is a line that has a 180 degree on there. So 180 - 74 and divide that by 2 to find X and Z. 180 - 74 is 106. 106/2 = 53. Therefore, X and Z are 53 degrees, Y is 74 degrees.
Answer: Bottom left corner
The four rectangles stacked vertically form the lateral sides of the rectangular prism. The rectangles on the far left and far right sides form the base faces. I recommend printing out each design (or drawing them), cutting them out, and trying to fold them up.
The volume of a cone is calculated through the equation,
V = (πD²/4)(H)/3
where V is volume,
D is diameter
H is height
Substituting the known values,
V = (π(3m)²/4)(4m)/3
Simplifying,
V = 3π m³
The volume of the cone is equal to 3π or 9.42 m³. The value should complete the volume statement of the cone.
