Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
To do this, you want to subtract each of the zeroes from x and multiply them together. Like this: (x-7)(x-(-11))(x-(2+8i)). When you multiply it out you should get the answer.
Answer:
The measure of angle A is 35°
The measure of angle B is 90°
The measure of angle C is 55°
Step-by-step explanation:
Let
x -----> the measure of angle A
y ----> the measure of angle B
z ----> the measure of angle C
we have
Observing the ratio
The smallest angle is x and the greatest angle is y
In a right triangle, the measure of the right angle is the greatest angle and the sum of the other two angles is equal to 90 degrees, because are complementary angles
so
y=90° -----> equation A
x+z=90° -----> equation B (by complementary angles)
x=35° -----> equation C (the smallest angle)
Substitute the value of x in equation B and solve for z
35°+z=90°
z=90°-35°=55°
therefore
The measure of angle A is 35°
The measure of angle B is 90°
The measure of angle C is 55°
