The temperature in Saginaw is 70°F and is decreasing at a rate of 2° per hour. The temperature in Decatur is 68°F and is decreasing at a rate of 1.5° per hour. Find h, the number of hours until the temperature in Saginaw and Decatur is the same.

it's both, now can you answer my most recent question?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
