It is A, 60° because 180° (degree of the whole triangle) divided by the three angles is 60.
Properties of Logs
logb(x/y) = log<span>bx</span> - log<span>by</span>.
therefore
log5 (4/7)= log5 (4)- log5 (7)
<span>Solve log 5 (4) and log 5 (7) with the base change of the logarithm</span>
<span>log 5 4 = log 4 / log 5 </span>
Use the calculator:
<span>
<span>log 5 4 =0.8613531161
</span></span>
log 5 7 = log 7 / log 5
<span>log 5 7 =1.2090619551</span>
<span>log5 (4/7)= log5
(4)- log5 (7)=-0.347708839</span>
An inch or 2 so yeah if in shapes then around a rectangle
Using the Pythagoras theorem
8^2 = 5^2 + x^2 where x = 1/2 length of the base
x^2 = 64-25 = 39
x = = sqrt39 = 6.24
so base length = 2*6.24 = 12.5 cm to nearest tenth
It is m4 in my opinion i’m not sure tho
