The Pythagorean theorem states that a² + b²= c². this theorem only works with RIGHT TRIANGLES, and thats all.
i don't think dilations has a formula, unless you count the scale factor as its formula.
Answer:
y = 10
Step-by-step explanation:
-7x + 3y = 30
(-7 x 0) + 3y = 30
0 + 3y = 30
3y = 30
y = 10
If D is the center of the circle, ∠ADB = 70°, as that is where the arc gets its measure.
If D is on the circle and not on the arc, ∠ADB = 35°, half the measure of the arc's central angle.
If D is on arc AB, then ∠ADB = 145°, half the measure of the corresponding central angle.
If D is inside or outside the circle (and not one of the above), we need to know more about the measures of arcs intercepted by lines AD and BD.
Answer:
Step-by-step explanation:
CBA = 31
BAC = 59
31 + 59 = 90
The two angles = 90 degrees.
There are complementary.
