Answer:
71°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠H = 180° -109° = 71°
_____
<em>Additional comment</em>
The above rule comes from the more general rule that the measure of an inscribed angle is half the measure of the arc it intercepts. Here, inscribed angle J intercepts arc GHI, so that arc has measure 2×109°. Then the measure of short arc GI is 360° -2×109°, and inscribed angle H is half that:
∠H = (1/2)(360° -2×109°)
∠H = 180° -109° = 71°
256 is the perfect square of 16 it would be 66 square root a2b
Answer:
C. 120
Step-by-step explanation:
Hope it helps!
"total" means "sum" more or less, so the total of m and 10 is m+10
The square of this is (m+10)^2
----------------------
If you want to expand this out, then you would get
(m+10)^2 = (m+10)(m+10)
(m+10)^2 = A(m+10) ... let A = m+10
(m+10)^2 = A*m + A*10
(m+10)^2 = m(A) + 10(A)
(m+10)^2 = m(m+10) + 10(m+10) .... plug in A = m+10
(m+10)^2 = m^2+10m+10m+100
(m+10)^2 = m^2+20m+100
Of the 98 butterflies cataloged, 8 were giant swallowtails. If about 5 times as many butterflies visit, we expect about 5 times as many to be giant swallowtails.
5*8 = 40
The appropriate choice is ...
A. 40
