Answer:
32/40
Step-by-step explanation:
1: Sin= Soh
Soh= Opposite over Hypotenuse
2. A's opposite is 32
3. A's Hypotenuse is 40
4. A = 32/40
Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)
Answer:
it would be y= -7
Step-by-step explanation:
The mistake he made was that he did not consider units of measurement while comparing the lengths
He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
Step-by-step explanation:
Length of desk = 1 meter
Henry's name tag = 8 cm
Henry says that his name tag is 7 cm longer than the desk. The mistake he made was that he did not compare the units of both quantities. He just subtracted 1 from 8 and got 7. Meter is a larger unit and centimeter is a smaller unit. In order to compare the lengths of the desk and his name tag the units have to be same.
Hence
The mistake he made was that he did not consider units of measurement while comparing the lengths
He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
