Touris mathematics test had 75 problems, 10 arithmetic, 30 algebra, 35 Geometry problems.Although she answered 70% of the arithmetic, 40% of the algebra, and 60% of the geometry problems correctly she did not pass the test because she got less than 60% of the problems rate how many more questions would she need to have answered correctly to earn a 60% passing grade

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
