Find the m Exterior angle of triangle

Mathematics
1 answer:
Lera25 [3.4K]2 years ago
8 0

Answer:

60 degrees

Step-by-step explanation:

ebd + dbc = 180 because they make a straight line

120 + dbc = 180

dbc = 60

the three angles in a triangle always add up to 180 degrees

bcd + dbc + cdb = 180

60 + 60 + cdb = 180

120 + cdb = 180

cdb = 60

Answer:

35.0 cm (to 3 significant figures)

Step-by-step explanation:

Circumference of a circle = 2d (where d is the diameter).

Since the rectangle is inscribed in the circle (all 4 vertex touch, but not intersect, the circumference of the circle), we can see that the diameter of the circle is in fact the diagonal of the rectangle.

Therefore, to calculate the circumference we need to find the diagonal of the rectangle and plug it into the above formula.

To find the diagonal, we use Pythagoras' Theorem a² + b² = c²  (where a and b are the legs, and c is the hypotenuse of a right angled triangle).

From inspection, the diagram has given us the lengths of the legs as 9cm and 15cm.  So:  

 9² + 15² = c²

81 + 225 = c²

      306 = c²

             c = √306 = 3√34

Therefore, the diameter of the circle = 3√34 cm

Circumference = 2d

                         = 2 x 3√34

                         = 6√34

                         = 35.0 cm (to 3 significant figures)

Describe how to decide if 94 is a prime number or a composite number
loris [4]
94 is a composite number. It is composite because it has more prime factors than just one and itself. 1,2,47,and 94 are the prime factors of 94.

Idk geometry so.. help pls
sashaice [31]
Um not fully confident which is funny because imma freshman but i believe you combined all the like terms to get “180 = 23x - 188” and it equals 180 in the end because it’s a straight line so anyways once you solve the problem you should get 16 i believe and if you’re confused just feel free to ask me and i hope i wasn’t too late to answer it
