Answer:
27
Step-by-step explanation:
Replace the x in f(x) by g(x) to get (f o g)(x)
= 2(4x - 3) - 7
= 8x - 6 - 7
= 8x - 13
so (f o g) (5)
= 8(5) - 13
= 27
If the triangle is an equilateral triangle the angles should be all 60 as (60+60+60=180) if that’s true then a congruent line from the triangle would form a 60 degree angle.
so x=60°
Answer:
405/14
Step-by-step explanation:
C^2=a^2+b^2-2abcosC
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°
$24.89
23x0.0822=1.89
23+1.89=24.89
