Answer:

  3. ΔABC ≅ ΔCDA. Reason: HL postulate

Step-by-step explanation:

The two triangles are right triangles (∠B ≅ ∠D = 90°) and one leg (BC, DA) and the hypotenuse (AC, CA) are shown to be congruent. So, the HL postulate applies. The only step needed is to refer to that postulate.

  Step 3. ΔABC ≅ ΔCDA. Reason: HL postulate

I need help with this I will appreciate if I get an answer for this problem
iragen [17]

Answer:

what's the problem!?......

angle CDT is the opposite angle of ADN

and the segment DF=FN, so AD= AN

and thats why angle FAN= angle FAD

here, Angle FAN =60,

therefore, FAD=60, and AFD = 90 so angle ADN must be 30 degree

and the opposite of ADN is CDT, and the opposite angles are equal.

Hope u got it.

A company plans to build at least 152 igloos in a single week by employing skilled workers from the cities of Tomsk and Kyzyl. A
Nikolay [14]

Answer:

each Tomskians will build 6 igloos per week

each Kyzylians will build 5 igloos per week

They achieved their goal

Step-by-step explanation:

6T + 5K ≥ 152

T = Tomskians

and each Tomskians will build 6 igloos per week

K = Kyzylians

and each Kyzylians will build 5 igloos per week

This is found by taking the coefficient on the inequality.

Substituting the values of T =10 and K = 19

6T + 5K ≥ 152

6*10 + 5*19  ≥ 152

60 + 95

155  ≥ 152

This is true, so they hired enough people.

In each diagram shown below, solve for the length of side CD using the information given. Show the trig ratio you use and your a
pishuonlain [190]

Applying the trigonometry ratios, we have:

a. CD = 63.6

b. CD = 33.8

c. CD = 16.1

d. CD = 15.9

<h3>What are the Trigonometry Ratios?</h3>

The trigonometry ratios are used to find a length or angle in any right triangle. They are:

  • SOH, which is sin ∅ = opp/hyp
  • CAH, which is cos ∅ = adj/hyp
  • TOA, which is tan ∅ = opp/adj

a. ∅ = 32°

hyp = 75

adj = CD

Apply CAH:

cos 32 = CD/75

CD = cos 32 × 75

CD = 63.6

b. ∅ = 56°

opp = 28

hyp = CD

Apply SOH:

sin 56 = 28/CD

CD = 28/sin 56

CD = 33.8

c.  ∅ = 43°

opp = 15

adj = CD

Apply TOA:

tan 43 = 15/CD

CD = 15/tan 43

CD = 16.1

d.  ∅ = 27°

hyp = 35

opp = CD

Apply SOH:

sin 27 = CD/35

CD = sin 27 × 35

CD = 15.9
