Step-by-step explanation:
Rule is that you just have to match up the corrisponding numbers and exponents to make the right expression. Hope i'm right.
95 times 2 is 190.
90 times 2 is 180, and 5 times 2 is 10.
180 + 10 = 190.
Answer:
78.5cm^2
Step-by-step explanation:
Half your diameter to get a radius.
D = 10cm
10 divided by 2 = 5
Pi (3.14)
3.14 x 5^2
3.14 x 25 = 78.5cm^2
Answer:
16.5 =x
Step-by-step explanation:
Since this is a right triangle, we can us trig functions
tan theta = opp side / adjacent
tan 70 = x /6
Multiply each side by 6
6 tan 70 = x
16.48486452 =x
To the nearest tenth
16.5 =x
The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. The formula that expresses the relation of the sides of the polygon and the measurement of the interior angle is (n2)*180/n where n is 7. Each interior angle then measures 128.6 degrees.
