The picture shows the Alamillo Bridge in Seville, Spain. In the
picture, mZ1 = 58°. Find the
measure of the supplement of
21.

122°

Step-by-step explanation:

Supplementary angles add to 180 degrees.

We know that ∠1 measures 58 degrees. We want to find the measure of the supplement, which we can call x. Since they are supplementary, they should add to 180 degrees.

∠1 + ∠x = 180

58 + ∠x= 180

We are trying to find the supplement, also known as x. Therefore, we must isolate x.

58 is being added to x. The inverse of addition is subtraction. Subtract 58 from both sides of the equation.

58-58+∠x=180-58

∠x=122

supplement= 122°

The supplement of angle 1 is 122 degrees.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
