Remember
the exterior angle=sum of the other 2 interior anlges

therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27


other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52

All I did was add all A's, B's, and C's separately. Than I added them all together and got 316 total surface area. I tried but I learned this sooo long ago so i'm sorry if you get it wrong. Good Luck!

A certain drug treatment cures 90% of cases of hookworm in children.18 Suppose that 20 children suffer- ing from hookworm are to
Anni [7]

Answer:

Step-by-step explanation:

Here X the no of children suffering from hookworm treated and recovered is binomial because

a) Each child is independent of the other

b) There are only two outcomes

c) The probability for any child to recover is constant as 90% = 0.9

X is Bin (20,0.9)

a) Prob that all 20 will be cured

=P(X=20)=0.9^{20} \\=0.1216

b) Prob all but 1 will be cured=P(x=1) = 20C1 (0.9) (.1)^{19} \\=1.8(10^8)

c) Prob exactly 18 will be cured

=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852

d) Prob exactly 90% will be cured.

=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852

An exterior angle of an isosceles triangle has measure 150 degrees. Find two possible sets of measures for the angles of the tri
AVprozaik [17]
Is it exterior as in on a line?? because 150 in a 360 angle is too small because 3601 -150 = 210 and that's too big for a triangle as it exceeds the rule of all angles in triangles add up to 180
