Please help I suck at math and I am so stressed with this question that I am literally on the verge of crying

608 cm²

Step-by-step explanation:

Find the area of the 3 rectangles.

Rectangle 1 = 10 x 16 = 160

Rectangle 2 = 16 x 12 = 192

Rectangle 3 = 16 x 10 = 160

Now find the area of the triangle using the formula:

x Base x height

= x 8 x 12 = 48

Both the triangles are similar, so you don't have to calculate again.

Finally add all the areas to get the surface area.

160 + 192 + 160 + 48 + 48 = 608 cm²

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
