4. figure A is a trapezoid the parallel sides are the bases and the other sides are the legs.
5. sum of interior angles is 360 to find the other answer subtract all known angles from 360.
6. figure B is a parallelogram. if angles are congruent that means they have the same measure. so if angle 1 is 128 then and 4 is 128.
7. the definition of a square : all interior angles each measure 90 degrees.
8. nonconsecutive means they aren't next to each other so in figure D angles d and b and angles a and c for figure E angle j and m and angle n and l
9. figure e is concave that means its got an angle that "caves in"
Answer:
represents the lateral surface area of the cone.
Step-by-step explanation:
Lateral surface area of cone(L) is given by:
.....[1]
where,
r is the radius of the cone
l is the slant height of the cone.
As per the statement:
A right cone with radius r and slant height s.
⇒
Substitute in [1] we have;
Therefore, represents the lateral surface area of the cone.
0.2 is also 20% hope this helps
Answer:
C
Step-by-step explanation:
Pythagorean theorem states that a^2 + b^2 = c^2. Let the length of the legs be x, so 2x^2 = c^2. c is the hypotenuse, which means that 2x^2 = 64. Divide both sides by 2, and we get x^2 = 32. Square root both sides and we get sqrt 32 or 4 * sqrt 2.
Answer:
c=-9.75
