D is the answer to this question i learned this last year
Answer:
If they're congruent, it would be the same length as side BC.
If they're similar, it would be the side of BC adjusted to whatever the ratio is
Answer:
108 degrees
Step-by-step explanation:
Given the following angle measures in triangle QRS
m<Q = 1x
m<R = 3x
m<S = 6x
Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees
The sum of angle in a triangle is 180 degrees
m<Q + m<R + m<S = 180
1x + 3x + 6x = 180
10x = 180
x = 180/10
x = 18
The obtuse angle is 6x
Measure of the obtuse angle = 6x
Measure of the obtuse angle = 6(18)
Measure of the obtuse angle = 108 degrees
Hence the measure of the obtuse angle is 108 degrees
It sets a condition: When thex and y units add to 90, tanx= recoprocal of tany
The chart gives the values of trig. function when at certain degrees. When we looks ar tanΘ, we are given the x and y values, becuase tanΘ= y/x
