The third angle of an isosceles triangle is 16 o less than the sum of two equal angles. Find

vodka [1.7K]

Answer: 49°, 49°, 82°

Step-by-step explanation:

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

4x - 16 = 180

4x = 196

x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82

Find the surface area

mote1985 [20]

Answer:

Step-by-step explanation:

l = 7 in

w = 11 in

h = 5 in

Surface area = 2*(lw +wh +hl)

= 2*(7*11 + 11*5 + 5*7)

= 2* (77+ 55 + 35)

= 2 * 167

After cross multiplication, you should end up with this equation

$4x=36$

After dividing 4 on both sides, you should get that x=9
