Eric drew an obtuse angle which of the following can be true for erics triangle. all 3 have equal measures, possible angle measures of the triangle are 92 degree 48 degree and 40 degree, 2 of the angles are equal and the 3rd angle is 70 degree, one angle has a measure of 90 degree while the other 2 angles measure less than 90 degrees

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
