Answer:
5.83
Step-by-step explanation:
Pythagorean Theorem a^2 + b^2 = c^2
1-14, You're just dividing. Like #1, -14÷2=-7 (negative fourteen divided by two, equals negative seven). A positive and a positive make a positive, a negative and a positive make a negative, a negative and a negative, make a positive. The word problems your also dividing, for example, #15, -40÷4=-10. Use the numbers that are given to you.
See the attached figure to better understand the problem
we know that
1) First way to find the value of ain the triangle ABC
<span>applying the Pythagorean theorem
AC</span>²=AB²+BC²--------> BC²=AC²-AB²-----> BC²=25²-15²-----> BC²=625-225
BC²=400--------> BC=20 units
a=BC
a=20 units
2) Second way to find the value of a
in the triangle ABD
AB²=AD²+BD²--------> BD²=AB²-AD²-----> BD²=15²-9²---> BD²=144
BD=12 units
in the triangle BDC
a=BC
BC²=BD²+DC²-----> 12²+16²----> 144+256------> BC²=400
BC=20 units
a=20 units
Answer:
See below for answer.
Step-by-step explanation:
RP/RT =RQ/RS Given
∠R = ∠R
ΔPQR similar to Δ TSR If the measures of two sides of a triangle are proportional to the measures of two corresponding sides of another triangle and their included angles are congruent, then the triangles are similar.
