Find two consecutive positive integers such that the sum of their squares is 145

Mathematics
1 answer:
DerKrebs [107]3 years ago
7 0

Answer:

8,9

Step-by-step explanation:

(x)^2+(x+1)^2=145

x²+x²+2x+1=145

2x²+2x+1-145=0

x²+x-72=0

x²+9x-8x-72=0

x(x+9)-8(x+9)=0

(x+9)(x-8)=0

x=-9(rejected being negative)

x=8

x+1=8+1=9

Find the value of x<br><br>m&lt;2= 10x + 10<br>​
jarptica [38.1K]

Answer:  x = 12

<u>Step-by-step explanation:</u>

a) Linear Pair: 110° + ∠a = 180°  -->    ∠a = 70°

b) congruent sides implies congruent angles  --> ∠b = 70°

c) Triangle Sum Theorem: ∠a + ∠b + ∠c = 180

                                         70° + 70° + ∠c = 180°

                                                            ∠c = 40°

d) Complimentary Angles: ∠c + ∠d = 90°

                                          40° + ∠d = 90°

                                                   ∠d = 50°

∠2) Linear Pair: ∠d + ∠2 = 180°

                         50° + ∠2 = 180°

                                  ∠2 = 130°

x) m∠2 = 130°

   10x + 10 = 130°

   10x        = 120

       x        = 12
