Which statements are true for the image below? Check all that apply.
A triangle has angles C, A, 33 degrees. The exterior angle to angle with measure of 33 degrees is D, the exterior angle to A is B, the exterior angle to angle C is 128 degrees.
Measure of angle B = measure of angle C + 33 degrees
Measure of angle B = 180 degrees minus (measure of angle D + 128 degrees)
Measure of angle B = 360 degrees minus (measure of angle D + 128 degrees)
Measure of angle D + measure of angle B + 128 degrees = 360 degrees
180 degrees = measure of angle D + measure of angle B + 128 degrees = 360 degrees
Measure of angle D = 360 degrees minus 33 degrees
Measure of angle D = 180 degrees minus 33 degrees
Measure of angle B = measure of angle D + 128 degrees

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
