Answer:

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

Answer:

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

The center of a cricle ids (h,7) and the radius is 10. The circle passes through (3,-1). Find all possible values of h.

Nostrana [21]

$center\ of\ a\ circle:(a;\ b)\\\\radius:r\\\\(x-a)^2+(y-b)^2=r^2\\\\========================\\\\(h;\ 7);\ r=10\\\\(x-h)^2+(y-7)^2=10^2\\\\========================$

$The\ circle\ passes\ throught\ (3;-1).\\\\Substitute\ x=3\ and\ y=-1:\\\\(3-h)^2+(-1-7)^2=100\\\\(3-h)^2+(-8)^2=100\\\\(3-h)^2+64=100\ \ \ /-64\\\\(3-h)^2=36\iff3-h=\pm\sqrt{36}\\\\3-h=-6\ or\ 3-h=6\\-h=-6-3\ or\ -h=6-3\\-h=-9\ or\ -h=3\\h=9\ or\ h=-3\\\\Answer:h=9\ or\ h=-3$

The bases on a baseball diamond are 90 feet apart. how far is it from home plate to second base?

Karolina [17]

See diagram

so we got a right triangle

so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²

so the legs are 90 and 90
hytponuse is distance from home to 2nd

so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c

127.279ft
about 127ft
