Answer:
-7
Step-by-step explanation:
3x +17 + 5x = 7x +10
3x +17 + 5x - 7x = +10-17
x=-7
Answer:
17 inches
Step-by-step explanation:
Pythagorean Theorem: a²+b²=c²
a²=90.25
b²=196
c²=286.25
c=length of diagonal
c=16.9189243
c≅17 inches
One <em>correct answer</em> is:
Let <em>m </em>and <em>n </em>be lines that intersect line <em>a</em>. Let <em>m</em> be perpendicular to <em>a</em>. This means that all 4 of the angles formed by the intersection of <em>m</em> and <em>a</em> are 90°.
Let <em>n</em> be perpendicular to <em>a</em>. This means that all 4 of the angles formed by the intersection of <em>n </em>and <em>a</em> are also 90°.
Since all of the angles are congruent, this means that the same-side interior angles (between lines <em>m</em> and <em>n</em>) are congruent. If two same-side interior angles are congruent, then the lines are parallel.
Formula is A=1/2bh so answer will be 27 divided by 2
<span>q =r/2(s+t) for t
</span><span>2q =r(s+t)
2q = rs + rt
rt = 2q - rs
t = 2q/r - s
