Answer:
108 degrees
36 degrees
72 degrees
trapezoid
Step-by-step explanation:
Since is a right triangle use the Pythagorean theorem to find the missing length in the triangle
17² =8² +x²
x²=17² -8²
x² =289-64=225
x=√225=15
Area of the triangle is 8·15/2=60 cm²
Answer:
6.28 cm
Step-by-step explanation:
The formula for the circumference of a circle with radius r is C = 2*pi*r.
If we let pi = 3.14 and r = 1 cm, then the circumference of this circle is
C = 2(3.14)(1 cm) = 6.28 cm

We'll use the Pythagorean Theorem (otherwise known as the Distance Formula):
Going from Q to P, x increases by 1 and y increases by 7. Thus, the component form of QP is <1,7>, and the magnitude of this vector is √(1^2+7^2) = 5√2.
Note: this is equivalent to <1, 7>, square root of 50.
