Resposta
The measure of the larger angle is 40 degrees.
Explicação
## Step 1Let's denote the larger angle as
and the smaller angle as
. According to the problem, the larger angle is twice the smaller angle minus 30 degrees. This can be written as:###
## Step 2We also know that the sum of the two angles is 90 degrees, which is the definition of complementary angles. This can be written as:###
## Step 3We can substitute the expression for
from Step 1 into the equation from Step 2, which gives us:###
## Step 4Solving this equation for
gives us the measure of the smaller angle.## Step 5Substituting the value of
into the equation from Step 1 gives us the measure of the larger angle.
