Do the following
find a common denominator 5x8=40
get all your denominator values the same
next solve
(5×15)+(8×2)+(5×(-7))/(40)

so you get this next
75+16-35/(40)

then you have
56/40

which reduces down to
7/5

If the difference between the measures of the two smaller angles of a right triangle is 20 degrees what is the measure, in degre
nordsb [41]

Answer:

Measure of the smallest angle = 35 degrees.

Step-by-step explanation:

As it is a right triangle the values of the 2 smaller angles will add up to 90 degrees.

So  the 2 angles can be written as x and 90-x and  we have:

(90 - x) - x = 20

-2x = 20 - 90 = -70

x = 35.

So the 2 angles are 35 and 55 degrees.

Answer:

The answer is C because how much each girl paid for each pound of cherries has the variable C attached, and the rest of the money spent added to it. Also looking in the equation the sign tells us that they paid the same price for everything totaled in all.

Can someone please explain<br> AAS<br> SAS<br> SSS<br> ASA <br> CPCTC
Lostsunrise [7]

The Angle Angle Side postulate (often abbreviated as AAS) states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.

The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. For example: is congruent to: (See Solving SSS Triangles to find out more) If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

CPCTC is an acronym for corresponding parts of congruent triangles are congruent. CPCTC is commonly used at or near the end of a proof which asks the student to show that two angles or two sides are congruent. ... Corresponding means they're in the same position in the 2 triangles.
